There must 0:42 · have been almost 200 columns originally, 0:45 · all erected in the second or third 0:48 · centuries AD. 0:50 · Most, unfortunately, were felled long 0:52 · ago by scavengers trying to retrieve the 0:55 · lead that held their drums together. 0:58 · Let's uh take a closer look here. 1:02 · Many columns, as you can hopefully see 1:04 · from here, were fitted with brackets for 1:07 · honorific statues. 1:09 · Note the elaborate Corinthian capitals, 1:12 · some of which were ornamented with 1:14 · figures from Greek myth. 1:18 · The avenue heads off into those 1:21 · nondescript tower blocks. We're going to 1:23 · turn toward the sea and Sully's most 1:25 · remarkable feature, its concrete harbor. 1:34 · By the time its harbor was built, Soleie 1:36 · had renamed itself Pompeiopoulos in 1:39 · honor of Pompy the Great, who had 1:42 · cleared the surrounding seas of pirates. 1:45 · It consisted of an oval basin protected 1:48 · by a huge concrete breakwater based on a 1:51 · natural reef. The concrete that held 1:54 · rubble core together was true Roman 1:57 · concrete made from potana volcanic sand 2:02 · imported from the Bay of Naples. The 2:05 · concrete was capped with courses of 2:07 · stone blocks that were strongly clamped 2:09 · together. 2:10 · The harbor has silted over, making it 2:13 · hard to imagine how impressive this 2:15 · engineering marvel once was. 2:18 · We'll walk out to that breakwater where 2:20 · that guy is fishing for a better look. 2:24 · This is the surviving part of the 2:26 · breakwater. 2:27 · You can see the huge stone blocks that 2:29 · capped it 2:33 · and up ahead 2:36 · the concrete core. 3:00 · Not bad for 19th centuries with no 3:03 · maintenance. 3:13 · See here that the sea has cut deeply 3:15 · into the aggregate and conglomerate base 3:18 · here. 3:29 · Walk out to the edge where you can kind 3:30 · of see the shape of the lost harbor. 4:08 · A closer look at how the breakwater was 4:10 · made. It was faced with these huge stone 4:14 · blocks which were clamped together. 4:17 · You can see here the impressions left by 4:19 · the clamps, but the metal was dug away. 4:24 · Here's the reel core bonded with 4:26 · concrete. 4:28 · Here's a loose chunk so you can get a 4:30 · closer look. 4:34 · Well, that's a wrap. It's a ghost of 4:37 · what it was, but the ghost is still 4:39 · pretty impressive.
Interesting. And I learned something new. The word “fletcher”, now a common name, means an “arrow maker.” I didn’t know that.
