WEBVTT 00:00:00.000 --> 00:00:04.379 So what if I told you that the rough, unfinished, 00:00:04.839 --> 00:00:07.019 almost wild -looking stone you see on the bottom 00:00:07.019 --> 00:00:11.400 floors of historic downtown banks and grand courthouses, 00:00:12.140 --> 00:00:14.160 what if I told you that's actually the most expensive 00:00:14.160 --> 00:00:16.780 part of the whole building? It is, yeah. It's 00:00:16.780 --> 00:00:18.920 honestly this brilliant architectural illusion, 00:00:19.260 --> 00:00:21.760 and it's just hiding right in plain sight. Most 00:00:21.760 --> 00:00:23.699 people just walk right past these buildings every 00:00:23.699 --> 00:00:26.239 single day. Right. You just absorb the feeling 00:00:26.239 --> 00:00:29.440 of them. Exactly. You absorb the vibe. without 00:00:29.440 --> 00:00:31.980 realizing you are being visually manipulated. 00:00:32.219 --> 00:00:34.520 And that is exactly our mission for today's Deep 00:00:34.520 --> 00:00:36.759 Dive. We're taking a comprehensive architectural 00:00:36.759 --> 00:00:40.100 guide to decode this secret paradoxical language 00:00:40.100 --> 00:00:42.600 of stone. Because once you see this trick... 00:00:42.649 --> 00:00:44.810 You know, you will literally never look at a 00:00:44.810 --> 00:00:46.789 city street the same way again. You really won't. 00:00:46.850 --> 00:00:49.030 So today we're dissecting a concept called rustication. 00:00:49.369 --> 00:00:51.250 But we aren't just going to talk about rocks 00:00:51.250 --> 00:00:53.990 today. No, definitely not. We're exploring the 00:00:53.990 --> 00:00:56.490 psychology of power. We're looking at the extreme 00:00:56.490 --> 00:00:58.649 lengths people go to project wealth and really 00:00:58.649 --> 00:01:01.530 the evolution of this massive architectural inside 00:01:01.530 --> 00:01:04.879 joke. OK, let's unpack this. Because the core 00:01:04.879 --> 00:01:07.859 irony here is just incredible to me. When you 00:01:07.859 --> 00:01:09.659 hear the word rustic, you naturally think of 00:01:09.659 --> 00:01:11.920 something simple, right? Like a log cabin or 00:01:11.920 --> 00:01:14.659 something. Yeah, an unrefined farmhouse or just 00:01:14.659 --> 00:01:17.959 something forged by nature. But architectural 00:01:17.959 --> 00:01:20.739 rustication is the absolute opposite of simple. 00:01:20.879 --> 00:01:24.079 Oh, complete opposite. It is a deliberate mathematically 00:01:24.079 --> 00:01:28.799 calculated flex by the architects and the incredibly 00:01:28.799 --> 00:01:31.819 wealthy patrons who hire them. So to really understand 00:01:31.819 --> 00:01:34.840 the flex, we have to look at the physical mechanics 00:01:34.840 --> 00:01:37.400 of stone masonry first. Yeah, we have to ask, 00:01:37.500 --> 00:01:40.760 how do you actually prepare a stone for a high 00:01:40.760 --> 00:01:43.180 -end classical building? Because the standard, 00:01:43.379 --> 00:01:45.260 like the gold standard method, is something called 00:01:45.260 --> 00:01:47.739 ashlar masonry. Right, which is just a perfectly 00:01:47.739 --> 00:01:50.439 smooth stone block. Exactly. Think of ashlar 00:01:50.439 --> 00:01:53.790 like a perfectly manufactured giant gray Lego 00:01:53.790 --> 00:01:56.189 brick. Okay a giant Lego. Yeah and the stonemason 00:01:56.189 --> 00:01:58.469 cuts and sands every single side of the stone 00:01:58.469 --> 00:02:00.950 so that it's perfectly flush. When you stack 00:02:00.950 --> 00:02:03.150 them the joints between the stones virtually 00:02:03.150 --> 00:02:06.140 disappear. So it creates this seamless, unified, 00:02:06.299 --> 00:02:09.199 perfectly flat wall. Right. Which obviously takes 00:02:09.199 --> 00:02:11.419 immense skill and time to pull off. It looks 00:02:11.419 --> 00:02:14.780 super clean, highly refined. So what do they 00:02:14.780 --> 00:02:17.159 do differently for rustication, then? Well, with 00:02:17.159 --> 00:02:20.620 rustication, the mason takes that exact same 00:02:20.620 --> 00:02:23.439 premium block of stone. The same exact block. 00:02:23.719 --> 00:02:26.379 The exact same one. And they square off every 00:02:26.379 --> 00:02:29.300 side perfectly, so it still stacks securely, 00:02:29.759 --> 00:02:32.370 except for the front face. Oh, the part facing 00:02:32.370 --> 00:02:34.729 the stone. Exactly. The side the public sees 00:02:34.729 --> 00:02:37.349 is intentionally messed with. So they often cut 00:02:37.349 --> 00:02:40.189 these deep angled grooves around the edges of 00:02:40.189 --> 00:02:42.770 the visible face. So they're framing it, basically. 00:02:42.889 --> 00:02:45.069 Right. It's called a channel joint. It basically 00:02:45.069 --> 00:02:48.229 creates a thick, dramatic shadow border around 00:02:48.229 --> 00:02:50.590 every single block. They are loudly announcing 00:02:50.590 --> 00:02:52.430 the borders of the stone. They want you to see 00:02:52.430 --> 00:02:54.750 the individual pieces making up the whole wall, 00:02:54.750 --> 00:02:56.569 right? Yeah. And then they attack the center. 00:02:56.870 --> 00:02:59.669 That exposed central face is deliberately left 00:02:59.669 --> 00:03:03.000 rough. just totally raw looking. Yeah or sometimes 00:03:03.000 --> 00:03:06.000 it's patterned or sometimes it's carved to bulge 00:03:06.000 --> 00:03:09.180 outward like a swollen belly. The key here is 00:03:09.180 --> 00:03:12.759 that they're putting in extra labor. you know, 00:03:13.159 --> 00:03:16.479 extra hours of master craftsmanship specifically 00:03:16.479 --> 00:03:19.240 to make the stone look like it hasn't been finished. 00:03:19.340 --> 00:03:21.919 Which is wild. Like reading through the sources, 00:03:22.180 --> 00:03:24.939 the absolute best modern equivalent I could think 00:03:24.939 --> 00:03:29.000 of is buying a pair of pre -ripped, heavily distressed 00:03:29.000 --> 00:03:31.300 designer jeans. That is, yeah, that's actually 00:03:31.300 --> 00:03:33.740 a really good analogy. Right. Because you are 00:03:33.740 --> 00:03:36.400 paying a massive premium for a highly skilled 00:03:36.400 --> 00:03:40.419 craftsman. to labor over a material with specialized 00:03:40.419 --> 00:03:43.000 tools just to make it look naturally worn out. 00:03:43.039 --> 00:03:45.219 Or heavily weathered, yeah. You're paying extra 00:03:45.219 --> 00:03:47.840 for the illusion of ruggedness. It's a funny 00:03:47.840 --> 00:03:50.500 comparison, but it is remarkably accurate in 00:03:50.500 --> 00:03:53.340 terms of human psychology. I mean, the main difference 00:03:53.340 --> 00:03:56.699 is instead of a $200 pair of jeans, we are talking 00:03:56.699 --> 00:03:59.360 about a $20 million palace. Right, slightly higher 00:03:59.360 --> 00:04:01.270 stakes. It's just a bit. Yeah. But let's look 00:04:01.270 --> 00:04:02.930 at how that aesthetic evolved, because it wasn't 00:04:02.930 --> 00:04:05.430 always this artificial flex. It wasn't. No. If 00:04:05.430 --> 00:04:07.229 we go back to true medieval architecture, or 00:04:07.229 --> 00:04:09.449 even look at the massive stone bases of traditional 00:04:09.449 --> 00:04:12.849 Japanese castles, Dundas used rough, unfinished 00:04:12.849 --> 00:04:15.949 stone for a very practical reason. OK, let me 00:04:15.949 --> 00:04:17.889 guess. They just didn't want to spend the money. 00:04:18.430 --> 00:04:21.329 Like, why pay a guy to chip away at a rock for 00:04:21.329 --> 00:04:23.730 a week when you just need a thick wall to stop 00:04:23.730 --> 00:04:26.230 an invading army? Pure budget constraints, exactly. 00:04:26.430 --> 00:04:29.990 In medieval times, smooth ashlar was reserved 00:04:29.990 --> 00:04:32.589 for the interior of the church or the king's 00:04:32.589 --> 00:04:35.069 private chambers. The fancy rooms. Right. The 00:04:35.069 --> 00:04:37.850 massive defensive walls were rough just because 00:04:37.850 --> 00:04:40.990 it was cheaper and faster. But an interesting 00:04:40.990 --> 00:04:43.750 psychological shift happens by the late 13th 00:04:43.750 --> 00:04:46.660 century. Okay, what kind of shift? Well, a perfect 00:04:46.660 --> 00:04:49.560 example is the Palazzo Vecchio in Florence, which 00:04:49.560 --> 00:04:52.480 started construction in 1298. So right around 00:04:52.480 --> 00:04:54.600 the turn of century. Yeah. And because rough 00:04:54.600 --> 00:04:56.939 stone had been used on military fortresses and 00:04:56.939 --> 00:04:59.860 castles for centuries before that, the public 00:04:59.860 --> 00:05:03.100 mind inextricably linked that rough, heavy texture 00:05:03.100 --> 00:05:06.800 with military strength. Ah, I see. It became 00:05:06.800 --> 00:05:10.220 a visual synonym for unbreakable. Exactly. It 00:05:10.220 --> 00:05:13.139 transformed from a cost saving measure into a 00:05:13.139 --> 00:05:16.319 deliberate psychological aesthetic of sheer unyielding 00:05:16.319 --> 00:05:18.860 power. So put yourself in the shoes of an average 00:05:18.860 --> 00:05:20.939 citizen walking down a dirt street in Florence 00:05:20.939 --> 00:05:22.800 back then. Right. You're just a regular person. 00:05:22.970 --> 00:05:26.110 You look at a building with this massive visual 00:05:26.110 --> 00:05:29.430 weight, putting the heavy, aggressively textured, 00:05:29.810 --> 00:05:32.430 deeply shadowed stone right there on the ground 00:05:32.430 --> 00:05:35.470 floor, it gives the building a psychological 00:05:35.470 --> 00:05:38.269 anchor. It really does. You look at it and subconsciously 00:05:38.269 --> 00:05:41.329 think, well, there is absolutely no way I could 00:05:41.329 --> 00:05:43.430 ever break into that building. Right. It creates 00:05:43.430 --> 00:05:46.449 a narrative of impregnability, which brings us 00:05:46.449 --> 00:05:49.810 perfectly to the era that became completely obsessed 00:05:49.810 --> 00:05:54.120 with manipulating this narrative. Renaissance 00:05:54.120 --> 00:05:56.180 power play. This is where the story gets really 00:05:56.180 --> 00:05:58.360 dramatic, especially with the Medici family. 00:05:58.459 --> 00:06:00.000 Oh yeah, they wrote the book on this. If you 00:06:00.000 --> 00:06:01.939 want to talk about projecting power, you have 00:06:01.939 --> 00:06:04.800 to look at the Palazzo Medici Riccardi in Florence, 00:06:05.160 --> 00:06:08.500 built between 1444 and 1484. Because Florence 00:06:08.500 --> 00:06:11.319 during the 15th century was an incredibly volatile 00:06:11.319 --> 00:06:14.800 place. It was dangerous. Very. The Medici were 00:06:14.800 --> 00:06:17.939 a banking family holding immense political power, 00:06:18.379 --> 00:06:20.699 which meant they were constantly a target for 00:06:20.699 --> 00:06:23.839 rival factions, assassination plots, or just 00:06:23.839 --> 00:06:26.040 rioting mobs. So they needed a building that 00:06:26.040 --> 00:06:29.019 functioned like a military bunker. Exactly. But 00:06:29.019 --> 00:06:32.819 they also needed to look like highly cultured, 00:06:32.939 --> 00:06:36.339 legitimate civic leaders. So they created a formula. 00:06:36.839 --> 00:06:39.920 The ground floor of their palace is genuinely 00:06:39.920 --> 00:06:43.029 rugged. Very rugged. It's wildly irregular with 00:06:43.029 --> 00:06:46.009 huge terrifying chunks of stone projecting right 00:06:46.009 --> 00:06:48.430 out at the street. But as you look up to the 00:06:48.430 --> 00:06:51.129 second floor, the rustication gets smoother and 00:06:51.129 --> 00:06:53.569 flatter. It does. And by the time you reach the 00:06:53.569 --> 00:06:56.129 top floor where the family actually lived, the 00:06:56.129 --> 00:06:59.629 stone is perfectly smooth ashlar. So they established 00:06:59.629 --> 00:07:02.889 a physical gradient of civilization, heavy, violent 00:07:02.889 --> 00:07:05.730 and fortress -like at the bottom where the public 00:07:05.730 --> 00:07:09.040 and the riots are. And cultured. light and classical 00:07:09.040 --> 00:07:11.540 up at the top. That is so clever. And once that 00:07:11.540 --> 00:07:13.899 rough to smooth formula became the standard for 00:07:13.899 --> 00:07:16.680 every wealthy banker in Italy, the architects 00:07:16.680 --> 00:07:19.100 realized they had to step up their game. They 00:07:19.100 --> 00:07:21.360 couldn't just do the basic version anymore. Right. 00:07:21.519 --> 00:07:23.459 They didn't just follow the rules anymore. They 00:07:23.459 --> 00:07:25.800 started actively weaponizing them to show off. 00:07:25.939 --> 00:07:28.120 They started treating the architecture like an 00:07:28.120 --> 00:07:31.860 inside joke. Literally. So by the early 1500s, 00:07:32.339 --> 00:07:35.199 the architect Donato Bramante designs the Palazzo 00:07:35.199 --> 00:07:38.600 Caprini in Rome. OK, what did he do? He used 00:07:38.600 --> 00:07:41.519 rustication on the ground floor to create a massive 00:07:41.519 --> 00:07:44.240 blind arcade. And a blind arcade is basically 00:07:44.240 --> 00:07:46.759 a wall that is shaped like a series of structural 00:07:46.759 --> 00:07:48.779 arches, but the archways are actually filled 00:07:48.779 --> 00:07:52.000 in solid, right? Yes, exactly. So it looks incredibly 00:07:52.000 --> 00:07:55.120 strong, supporting smooth upper stories with 00:07:55.120 --> 00:07:58.629 these elegant Doric columns. But there's a secret. 00:07:58.870 --> 00:08:01.670 There is a big secret. Promonte didn't even use 00:08:01.670 --> 00:08:04.269 real stone for the heavy rustication. Wait, what? 00:08:04.490 --> 00:08:07.170 He used stucco, essentially a fine plaster to 00:08:07.170 --> 00:08:10.350 sculpt fake rough stones. Wait, wait. He faked 00:08:10.350 --> 00:08:13.069 the heavy stone flex on a literal palace. He 00:08:13.069 --> 00:08:15.250 totally did because the idea of the rough stone 00:08:15.250 --> 00:08:17.189 was more important than the stone itself. That 00:08:17.189 --> 00:08:19.889 is unbelievable. And then this group known as 00:08:19.889 --> 00:08:22.569 the Mannerist Architects came along and pushed 00:08:22.569 --> 00:08:24.910 this to the absolute limit. Right, Mannerism. 00:08:25.089 --> 00:08:27.629 Mannerism was essentially a movement where artists 00:08:27.629 --> 00:08:29.790 had mastered the classical rules of proportion 00:08:29.790 --> 00:08:31.870 so completely that they got bored. They just 00:08:31.870 --> 00:08:34.470 got bored of being perfect. Yeah, so they started 00:08:34.470 --> 00:08:37.929 warping the rules for dramatic, almost anxiety 00:08:37.929 --> 00:08:40.429 -inducing effects. And the prime suspect here 00:08:40.429 --> 00:08:43.370 is an architect named Giulio Romano. Giulio Romano 00:08:43.370 --> 00:08:47.909 at the Palazzo Te in Mantua. He took this massive 00:08:47.909 --> 00:08:50.610 classical building and literally played games 00:08:50.610 --> 00:08:53.269 with the stonework. What kind of games? Well, 00:08:53.669 --> 00:08:57.049 he mixed perfectly smooth ashlar blocks right 00:08:57.049 --> 00:08:59.649 next to aggressively projecting rough blocks. 00:08:59.840 --> 00:09:03.080 on the exact same wall. Just chaos. It gets weirder. 00:09:03.279 --> 00:09:06.080 He even placed larger, heavier -looking rusticated 00:09:06.080 --> 00:09:08.399 blocks higher up on the wall than the smaller 00:09:08.399 --> 00:09:11.159 ones, completely inverting the structural logic 00:09:11.159 --> 00:09:14.220 of gravity. Oh wow. Yeah, he even designed some 00:09:14.220 --> 00:09:16.830 massive stones in the arches to looked like they 00:09:16.830 --> 00:09:18.610 were slipping out of place and about to crush 00:09:18.610 --> 00:09:20.870 the viewer. But hold on, if they are just messing 00:09:20.870 --> 00:09:23.070 around with the stones, you know, putting heavy 00:09:23.070 --> 00:09:25.470 ones on top, mixing rough and smooth, making 00:09:25.470 --> 00:09:27.789 it look like the building is falling apart, doesn't 00:09:27.789 --> 00:09:30.210 it lose its meaning? How so? Like, doesn't it 00:09:30.210 --> 00:09:31.909 stop looking like a strong fortress and just 00:09:31.909 --> 00:09:33.970 start looking like a mess? What's fascinating 00:09:33.970 --> 00:09:36.490 here is that that is the genius of it. You have 00:09:36.490 --> 00:09:38.590 to ask who Romano was actually designing for. 00:09:38.720 --> 00:09:41.740 OK, who was it for? He wasn't designing to intimidate 00:09:41.740 --> 00:09:44.220 the average peasant on the street anymore. He 00:09:44.220 --> 00:09:47.279 was designing for highly sophisticated, ultra 00:09:47.279 --> 00:09:49.840 wealthy patrons who already knew the classical 00:09:49.840 --> 00:09:52.259 rules of architecture. Oh, so they were in on 00:09:52.259 --> 00:09:55.620 the joke. Exactly. By breaking the rules so deliberately, 00:09:55.879 --> 00:09:58.340 he was demonstrating absolute mastery over them. 00:09:58.600 --> 00:10:01.779 It's like a jazz musician intentionally playing 00:10:01.779 --> 00:10:04.740 discordant offbeat notes. Right, yes. You can 00:10:04.740 --> 00:10:06.940 only break the rules beautifully if the audience 00:10:06.940 --> 00:10:09.539 knows you've already mastered the scales. Architectural 00:10:09.539 --> 00:10:12.519 jazz. That's exactly what it was. And they became 00:10:12.519 --> 00:10:15.100 so obsessed with the rules of this jazz that 00:10:15.100 --> 00:10:17.299 later architectural writers like James Gibbs 00:10:17.299 --> 00:10:20.340 and William Chambers literally wrote textbooks 00:10:20.340 --> 00:10:22.960 trying to set strict mathematical proportions 00:10:22.960 --> 00:10:25.860 for the chaos. Textbooks on how to make fake 00:10:25.860 --> 00:10:28.159 rough rocks. Yeah, they tried to mathematically 00:10:28.159 --> 00:10:31.059 calculate exactly how wide the indented joints 00:10:31.059 --> 00:10:33.759 between the rough stones should be relative to 00:10:33.759 --> 00:10:35.759 the width of the smooth columns above them. They 00:10:35.759 --> 00:10:37.840 were trying to quantify an illusion. They really 00:10:37.840 --> 00:10:40.480 were. But the math clearly couldn't contain the 00:10:40.480 --> 00:10:43.460 madness. Because once every banker in Florence 00:10:43.460 --> 00:10:45.899 is putting rough stones on their ground floor, 00:10:46.460 --> 00:10:49.200 the rough look itself loses its exclusivity. 00:10:49.600 --> 00:10:52.799 It becomes common. Right. So if you are a billionaire 00:10:52.799 --> 00:10:55.639 patron in the Baroque era, how do you show off 00:10:55.639 --> 00:10:57.580 when everyone else is already doing the heavy 00:10:57.580 --> 00:10:59.840 stone trick? You have to attack the surface of 00:10:59.840 --> 00:11:02.639 the stone itself, the structural logic goes out 00:11:02.639 --> 00:11:05.759 the window, and this era of wild, obsessive, 00:11:05.879 --> 00:11:08.480 decorative texture begins. Here's where it gets 00:11:08.480 --> 00:11:10.779 really interesting, because the sources detail 00:11:10.779 --> 00:11:13.399 these bizarre variations. And I need you to explain 00:11:13.399 --> 00:11:15.299 how they actually did this, because it sounds 00:11:15.299 --> 00:11:18.000 frankly impossible. It's pretty wild. Let's start 00:11:18.000 --> 00:11:20.799 with vermiculation. What is that? Vermiculation 00:11:20.799 --> 00:11:23.740 comes from the Latin word for little worm. Little 00:11:23.740 --> 00:11:26.519 worm? Yeah. Masons would take specialized chisels 00:11:26.519 --> 00:11:30.340 and drills and painstakingly carve squiggly irregular 00:11:30.340 --> 00:11:33.259 deeply recessed tracks all over the face of the 00:11:33.259 --> 00:11:35.539 stone. So it ends up looking like worm casts 00:11:35.539 --> 00:11:37.779 and mud. Or like the trails insects leave under 00:11:37.779 --> 00:11:40.399 the bark of a dead tree. But why? Why would a 00:11:40.399 --> 00:11:42.860 royal family want their palace to look like it 00:11:42.860 --> 00:11:45.820 was eaten by giant worms? It connects to a broader 00:11:45.820 --> 00:11:49.000 philosophical obsession of the era. The Memento 00:11:49.000 --> 00:11:52.480 Mori. the reminder of death and decay. Oh, that 00:11:52.480 --> 00:11:55.539 makes sense. By making the eternal solid stone 00:11:55.539 --> 00:11:58.559 look as though time and biology were slowly eating 00:11:58.559 --> 00:12:01.720 away at it, it gave the building a sense of ancient 00:12:01.720 --> 00:12:04.559 romantic ruin right from the day it was finished. 00:12:04.779 --> 00:12:07.559 And the scale of this is just staggering. Oh, 00:12:07.559 --> 00:12:09.720 absolutely. If those worm tracks connect into 00:12:09.720 --> 00:12:12.279 a continuous web, the guide says it's called 00:12:12.279 --> 00:12:14.960 reticulated rustication. Right, reticulated. 00:12:15.059 --> 00:12:18.279 And the Turner Motholeum by James Gibbs uses 00:12:18.279 --> 00:12:20.889 this vermiculat - texture on over half of its 00:12:20.889 --> 00:12:23.690 main exterior. Just drilling little worm trails 00:12:23.690 --> 00:12:26.690 into solid rock for weeks. Incredible. And then 00:12:26.690 --> 00:12:28.889 you have frostwork. Frostwork is fascinating. 00:12:29.129 --> 00:12:32.230 They carve the stone to look like hanging icicles, 00:12:32.490 --> 00:12:34.850 stalactites, or drooping pondweed. And where 00:12:34.850 --> 00:12:37.529 would you see that? You see this heavily in garden 00:12:37.529 --> 00:12:40.750 architecture, grottoes and fountains, like London's 00:12:40.750 --> 00:12:43.129 Diana Fountain from the 1690s. Is that another 00:12:43.129 --> 00:12:45.549 decay thing, like the worms? Actually, it's the 00:12:45.549 --> 00:12:47.990 ultimate conquest of nature. Conquering nature. 00:12:48.370 --> 00:12:51.809 Yeah. They were forcing the heaviest, most permanent 00:12:51.809 --> 00:12:55.169 material on Earth's stone to mimic the most fragile, 00:12:55.309 --> 00:12:57.970 temporary states of water and vegetation. Oh, 00:12:57.970 --> 00:13:01.029 wow. It was mankind proving it could freeze nature 00:13:01.029 --> 00:13:04.210 in time. That's incredibly poetic. And if they 00:13:04.210 --> 00:13:07.309 wanted a different vibe, say, sheer untamed geology, 00:13:07.789 --> 00:13:11.429 they used cyclopean rustication. Cyclopean, like 00:13:11.429 --> 00:13:14.250 the cyclops? Exactly. They would use massive, 00:13:14.690 --> 00:13:17.389 highly irregular boulders that looked as if a 00:13:17.389 --> 00:13:19.610 mythical one -eyed giant had simply dropped them 00:13:19.610 --> 00:13:22.470 into a pile by accident. It's all so dramatic. 00:13:22.929 --> 00:13:24.950 But there's one style in the sources that feels 00:13:24.950 --> 00:13:27.529 almost visually aggressive. Diamond rustication. 00:13:27.710 --> 00:13:30.509 The diamond rustication, it is so striking. It's 00:13:30.509 --> 00:13:32.629 arguably the most striking one. Instead of leaving 00:13:32.629 --> 00:13:35.629 the stone rough or wormy, they carved the entire 00:13:35.629 --> 00:13:38.250 visible face of the block into a low three -dimensional 00:13:38.250 --> 00:13:40.649 pyramid pointing right out at the viewer. It 00:13:40.649 --> 00:13:42.149 makes the entire wall look like it's covered 00:13:42.149 --> 00:13:44.370 in spikes. It really does. Where did that even 00:13:44.370 --> 00:13:45.990 come from? It doesn't look classical at all. 00:13:46.169 --> 00:13:48.730 It isn't classical. It actually traces its roots 00:13:48.730 --> 00:13:51.830 back to late Gothic styles, specifically the 00:13:51.830 --> 00:13:54.750 Iberian manual line or Isabelline Gothic styles 00:13:54.750 --> 00:13:58.789 from Spain and Portugal. Oh, those styles were 00:13:58.789 --> 00:14:01.970 heavily inspired by the hyper ornate three dimensional 00:14:01.970 --> 00:14:05.289 surface textures of Moorish design. So they borrowed 00:14:05.289 --> 00:14:07.929 it. Yeah. The Renaissance architects took that 00:14:07.929 --> 00:14:10.809 raised Gothic decoration and adapted it into 00:14:10.809 --> 00:14:13.429 their classical stone grids. And they applied 00:14:13.429 --> 00:14:15.970 this to massive buildings. I mean, the Palazzo 00:14:15.970 --> 00:14:19.210 dei Diamanti in Ferrara is completely covered 00:14:19.210 --> 00:14:22.090 in these stone diamonds. Yes. The Palace of Facets 00:14:22.090 --> 00:14:25.590 in the Moscow Kremlin, built in the 1490s, uses 00:14:25.590 --> 00:14:28.470 them across its entire facade. Just imagine the 00:14:28.470 --> 00:14:30.929 labor. Seriously, think about the physical reality 00:14:30.929 --> 00:14:33.470 of that for a second. Think about the last time 00:14:33.470 --> 00:14:35.149 you tried to carve something out of wood with 00:14:35.149 --> 00:14:37.549 a knife. It's not easy. Now imagine sitting in 00:14:37.549 --> 00:14:40.070 the blinding Italian sun for 10 hours a day, 00:14:40.490 --> 00:14:42.809 hitting a steel chisel against solid rock with 00:14:42.809 --> 00:14:45.509 a heavy wooden mallet, breathing in stone dust, 00:14:45.850 --> 00:14:49.049 just to carve one perfect symmetrical three -dimensional 00:14:49.049 --> 00:14:51.470 spike. Right. Now look at a palace wall with 00:14:51.470 --> 00:14:54.570 10 ,000 of them. It is an overwhelming display 00:14:54.570 --> 00:14:57.450 of wealth, communicated entirely through the 00:14:57.450 --> 00:15:00.620 medium of human time. You are staring at thousands 00:15:00.620 --> 00:15:04.419 of hours of ruined hands and skilled labor frozen 00:15:04.419 --> 00:15:07.100 in stone. Which naturally brings us to the ultimate 00:15:07.100 --> 00:15:10.039 question. If this look is the ultimate symbol 00:15:10.039 --> 00:15:12.679 of wealth and power, and it becomes mandatory 00:15:12.679 --> 00:15:15.159 for public buildings across Europe, What do you 00:15:15.159 --> 00:15:16.919 do if you want the power, but you don't have 00:15:16.919 --> 00:15:19.419 the budget for 10 ,000 hand -carved stone diamonds? 00:15:19.659 --> 00:15:22.620 Exactly. What do you do? You fake it. You fake 00:15:22.620 --> 00:15:24.860 it. And the lengths people went to in order to 00:15:24.860 --> 00:15:27.600 fake this specific aesthetic are honestly inspiring. 00:15:28.220 --> 00:15:31.100 A perfect case study is 18th century New England. 00:15:31.440 --> 00:15:33.919 Okay. Crossing the Atlantic. Right. American 00:15:33.919 --> 00:15:36.799 colonists wanted their homes to reflect the Grand 00:15:36.799 --> 00:15:39.350 Palladian architectural style. Palladian meaning 00:15:39.350 --> 00:15:42.169 those highly symmetrical grand European buildings 00:15:42.169 --> 00:15:45.169 with columns inspired by ancient Roman temples. 00:15:45.570 --> 00:15:48.450 Exactly. But the problem was high quality stone 00:15:48.450 --> 00:15:51.649 and the master masons to carve it were incredibly 00:15:51.649 --> 00:15:54.370 rare and expensive in the early American colonies. 00:15:54.590 --> 00:15:57.169 So they were building primarily with wood. Mostly 00:15:57.169 --> 00:16:00.710 wood. Yeah. And the most famous example of someone 00:16:00.710 --> 00:16:03.350 solving this problem is George Washington at 00:16:03.350 --> 00:16:05.389 his Mount Vernon estate. I loved reading about 00:16:05.389 --> 00:16:08.200 this in the sources. The home of the first American 00:16:08.200 --> 00:16:11.059 president is essentially a giant architectural 00:16:11.059 --> 00:16:13.980 optical illusion. It really is. He wanted his 00:16:13.980 --> 00:16:17.080 wooden house to look like a European stone mansion. 00:16:17.460 --> 00:16:20.139 So his carpenters used this brilliant three -step 00:16:20.139 --> 00:16:22.720 process. Yes, step one. First, they would cut 00:16:22.720 --> 00:16:26.980 and sand thick wooden planks and then carve beveled 00:16:26.980 --> 00:16:29.340 grooves into the wood. So the planks literally 00:16:29.340 --> 00:16:32.000 mimicked the deep channel joints of rusticated 00:16:32.000 --> 00:16:35.000 stone blocks. So step one is basically physically 00:16:35.000 --> 00:16:37.740 mimicking the of the shadow of the stone. Right. 00:16:38.139 --> 00:16:40.679 Step two, they painted the wood with a heavily 00:16:40.679 --> 00:16:43.580 applied thick coat of oil paint. Okay. And step 00:16:43.580 --> 00:16:46.039 three, this is the genius part, while that paint 00:16:46.039 --> 00:16:48.340 was still wet, they would take literal sand and 00:16:48.340 --> 00:16:50.840 throw it. or air blasted onto the side of the 00:16:50.840 --> 00:16:53.440 house until the sand stuck to the paint. So clever. 00:16:53.799 --> 00:16:56.580 When it dried, that wooden wall had the exact 00:16:56.580 --> 00:16:59.360 coarse rough texture and visual weight of heavy 00:16:59.360 --> 00:17:02.419 stone. It's incredible. They manufactured the 00:17:02.419 --> 00:17:05.240 psychological weight of an ancient fortress using 00:17:05.240 --> 00:17:08.980 timber, wet paint, and beach sand. It's basically 00:17:08.980 --> 00:17:11.640 the 18th century version of putting a carbon 00:17:11.640 --> 00:17:14.740 fiber vinyl wrap on a cheap Honda Civic. Oh, 00:17:14.740 --> 00:17:17.319 absolutely. George Washington was wrapping his 00:17:17.319 --> 00:17:19.680 wooden house to look like a European supercar. 00:17:19.799 --> 00:17:22.980 That is exactly what he was doing. And this desire 00:17:22.980 --> 00:17:25.700 to fake the aesthetic was a global phenomenon. 00:17:26.220 --> 00:17:28.359 Like in places like the Czech Republic, they 00:17:28.359 --> 00:17:31.099 achieved the look using a technique called scrafito. 00:17:31.559 --> 00:17:33.519 I've seen pictures of this. How does that work 00:17:33.519 --> 00:17:36.680 exactly? Scrafito was a plaster technique. they 00:17:36.680 --> 00:17:38.880 would lay down a layer of dark colored plaster 00:17:38.880 --> 00:17:41.019 on the exterior of the building. Okay, dark plaster 00:17:41.019 --> 00:17:43.619 first. Then, while it was still wet, they would 00:17:43.619 --> 00:17:46.099 lay a thin layer of light colored plaster over 00:17:46.099 --> 00:17:48.680 it. Oh, I see where this is going. Yeah, finally, 00:17:48.880 --> 00:17:51.019 artists would literally scratch and scrape away 00:17:51.019 --> 00:17:53.619 the top light layer to reveal the dark layer 00:17:53.619 --> 00:17:56.119 underneath. Wow! They used this scraping technique 00:17:56.119 --> 00:17:59.299 to draw a highly realistic two -dimensional optical 00:17:59.299 --> 00:18:02.059 illusion of three -dimensional diamond rustication. 00:18:02.220 --> 00:18:04.799 They were physically drawing the shadows of fake 00:18:04.799 --> 00:18:07.599 stones onto a flat wall. The trickery is just 00:18:07.599 --> 00:18:09.759 unbelievable. But wait, if we look at modern 00:18:09.759 --> 00:18:13.099 cities today, we can just build skyscrapers out 00:18:13.099 --> 00:18:15.420 of sheer glass and steel, right? Right. The technology 00:18:15.420 --> 00:18:17.559 is completely different. We don't need heavy 00:18:17.559 --> 00:18:19.799 stone at the bottom to hold up the building anymore. 00:18:20.180 --> 00:18:24.019 So why do I still see modern architects? putting 00:18:24.019 --> 00:18:27.900 fake stone bases or textured concrete on the 00:18:27.900 --> 00:18:30.940 bottom floors of new city center buildings? That's 00:18:30.940 --> 00:18:32.940 a great question. Are we still trying to look 00:18:32.940 --> 00:18:35.599 like medieval fortresses? Well, today it serves 00:18:35.599 --> 00:18:37.559 a different psychological purpose. I mean, in 00:18:37.559 --> 00:18:40.359 the late 19th century, architects like H. H. 00:18:40.500 --> 00:18:43.859 Richardson used massive. dark, rusticated stone 00:18:43.859 --> 00:18:47.039 arches to convey a sense of ancient permanence. 00:18:47.160 --> 00:18:50.299 Which we now call Richardsonian Romanesque. Exactly. 00:18:50.660 --> 00:18:52.779 But today, when an architect puts a rusticated 00:18:52.779 --> 00:18:55.859 base on a modern steel building, it's mostly 00:18:55.859 --> 00:18:59.079 used as a contextual tool. Contextual how? It 00:18:59.079 --> 00:19:01.980 helps a brand new, modern structure physically 00:19:01.980 --> 00:19:05.240 blend in and harmonize with the older, historic 00:19:05.240 --> 00:19:07.339 brick and stone streets around it. Oh, to be 00:19:07.339 --> 00:19:09.950 polite to the neighborhood. Yeah, it is a visual 00:19:09.950 --> 00:19:13.049 shorthand that says to the pedestrian, I respect 00:19:13.049 --> 00:19:15.589 the history of this street. I belong here. It 00:19:15.589 --> 00:19:18.569 is amazing to see how this journey unfolds. We 00:19:18.569 --> 00:19:20.950 started with a medieval cost saving trick, just 00:19:20.950 --> 00:19:22.990 leaving the stone rough because it was cheap. 00:19:23.009 --> 00:19:25.349 Right. Then it evolves into a Renaissance symbol 00:19:25.349 --> 00:19:28.410 of absolute military and financial power. Then 00:19:28.410 --> 00:19:30.650 it mutates. Yeah, it mutates into architects 00:19:30.650 --> 00:19:33.750 carving worm tracks and diamond spikes just to 00:19:33.750 --> 00:19:36.210 show off their mastery of the rules. And eventually. 00:19:36.490 --> 00:19:39.890 It becomes an aesthetic so undeniably vital to 00:19:39.890 --> 00:19:42.670 the concept of importance that founding fathers 00:19:42.670 --> 00:19:44.970 are out there faking it with sand and wood. It 00:19:44.970 --> 00:19:47.490 is the ultimate story of how human beings assign 00:19:47.490 --> 00:19:50.769 deep psychological meaning to mirror materials. 00:19:50.890 --> 00:19:53.509 It really is. So as we wrap up this deep dive 00:19:53.509 --> 00:19:55.829 into the hidden language of our cities, what 00:19:55.829 --> 00:19:58.329 is the big takeaway here? If we connect all of 00:19:58.329 --> 00:20:00.430 this to the bigger picture of how we live today, 00:20:00.940 --> 00:20:03.960 We have to recognize that for centuries, architecture 00:20:03.960 --> 00:20:07.319 utilized this very specific vertical narrative. 00:20:07.519 --> 00:20:09.400 The vertical narrative. Yeah, the rough, heavy, 00:20:09.559 --> 00:20:12.200 chaotic rustication at the bottom. Moving upward. 00:20:12.519 --> 00:20:15.660 to the smooth, refined ashlar at the top. So 00:20:15.660 --> 00:20:18.240 chaos to order. It was a physical narrative of 00:20:18.240 --> 00:20:21.359 human triumph. It represented mankind taming 00:20:21.359 --> 00:20:24.400 the wild, heavy earth at the ground level and 00:20:24.400 --> 00:20:27.119 ascending to achieve pure, classical perfection 00:20:27.119 --> 00:20:29.720 as the building reached toward the heavens. Right. 00:20:30.079 --> 00:20:32.299 It visually and psychologically anchored the 00:20:32.299 --> 00:20:34.380 building to the ground it stood on. But we just 00:20:34.380 --> 00:20:36.380 hit the ground with a sheet of glass now. There's 00:20:36.380 --> 00:20:39.799 no base, no middle, no top. Precisely. Today, 00:20:39.980 --> 00:20:41.960 our skyscrapers are built as perfectly smooth 00:20:41.960 --> 00:20:45.759 glass and steel extrusions. They are sheer, highly 00:20:45.759 --> 00:20:48.799 reflective surfaces from the pavement all the 00:20:48.799 --> 00:20:50.480 way to the clouds. It's totally detached. It 00:20:50.480 --> 00:20:52.400 raises a really important question about our 00:20:52.400 --> 00:20:54.619 environment. Like, have we lost our architectural 00:20:54.619 --> 00:20:56.619 connection to the roughness, the messiness of 00:20:56.619 --> 00:20:59.680 the earth? So here's a thought to consider long 00:20:59.680 --> 00:21:02.640 after we finish today. If modern builders were 00:21:02.640 --> 00:21:05.319 to invent a new form of rustication for the 21st 00:21:05.319 --> 00:21:08.460 century... A new anchor. Yeah, a new way to visually 00:21:08.460 --> 00:21:11.660 anchor our floating weightless glass towers to 00:21:11.660 --> 00:21:14.240 the heavy reality of the ground, what would that 00:21:14.240 --> 00:21:16.619 look like? How do you express the concept of 00:21:16.619 --> 00:21:19.579 rustication in an age of seamless glass? That 00:21:19.579 --> 00:21:21.960 is a fascinating question to leave on. Thank 00:21:21.960 --> 00:21:23.740 you so much for joining us on this deep dive. 00:21:23.839 --> 00:21:25.839 Thanks for exploring it with me. The next time 00:21:25.839 --> 00:21:28.440 you are walking downtown... Take a moment to 00:21:28.440 --> 00:21:30.480 look closely at the bottom floor of that bank 00:21:30.480 --> 00:21:33.859 or that historic courthouse. Run your hand over 00:21:33.859 --> 00:21:36.319 the stone. Look for the channel joints. See if 00:21:36.319 --> 00:21:38.700 you can spot the worms. Yes, look for the worms, 00:21:38.920 --> 00:21:42.019 the frost, the diamonds, or the deliberate illusion 00:21:42.019 --> 00:21:44.660 of simplicity. Because now you know that rough 00:21:44.660 --> 00:21:47.079 stone isn't just a rock, it's a very carefully 00:21:47.079 --> 00:21:48.079 crafted message.
