Two Roman Ships that Were Lost in WWII: What Destroyed the Floating Palaces of Emperor Caligula?

(Read the article on one page)

This is one of the most tragic stories about remarkable ancient artifacts you will ever read. After reading this article, you may have dreams about impressive ancient Roman ships that survived many centuries, only to be destroyed during World War II.

The ships built by the mad emperor Caligula in the 1st century AD looked like floating palaces. They were found at Lake Nemi and had everything that was characteristic of the hedonistic style of the Ptolemaic Period or the wealthy rulers of Syracuse (whose style inspired many bold feats in the ancient world.) This is what archaeologists recovered in 1929. However, fate soon gave the ships a tragic end.

Discovering Caligula's Ships

Caligula had many unique ideas about religion; he followed the cult of Isis, but also loved Alexander the Great and imagined he could be his reincarnation. Two of his biggest desires were to be richer and to create more luxurious buildings than his ancestors. It is unknown why Caligula decided to make these ships, but it was likely his vanity. The impressive ships had amazing treasures and incredible decoration. They were like floating palaces with mosaic floors, a heating system, marble decorations, baths, etc.

Lake Nemi is a small volcanic lake located in Lazio region. It is only 30 km (19 mi) south of Rome and was readily available to the ancient ruler of the Roman Empire.

The ships hadn't been lost for many centuries. Their location was known in the 15th century, when one of the most unexpected excavations in history took place. It is known that in 1446 an unusual expedition was led by Cardinal Prospero Colonna and Leon Battista Alberti. They analyzed resources and were able to locate the famous ships. At a depth of 18.3 meters (60 ft.), the first ''scuba divers'' tried to explore the site using a diving bell. The adventurous individuals who went to the sunken ships discovered bricks, copper, bronze, several artifacts, timber beams, and marble. The site became a source of precious artifacts. Most of them were sold and their fate remains unknown.

Some of the decorations from the Nemi ships: A bronze railing, a face, and brass rings recovered in 1895. These were fitted to the ends of cantilevered beams that supported each rowing position on the seconda nave.

After several centuries of this looting, professional researchers started to work on one of the most remarkable projects in the 19th century – the recovery of the two ancient ships. Finally, in 1927, by the order of the Italian dictator Benito Mussolini, the specialists drained the lake and recovered the ancient vessels. They became a fascinating topic for the media and the main feature of an incredible museum dedicated to their history.

The Legendary Ships of Beauty

The first ship, mentioned in the literature as Prima nave, was 70 meters (230 ft.) long with a beam width of 20 meters (66 ft.), while Seconda nave (the second ship) was 73 meters (240 ft.) in length and had a beam width of 24 meters (79 ft.).

What did they look like? Apart from the rich material related to excavations, we can use the description of the ship that inspired Caligula's builders. The famous ship of Ptolemy IV Philopator, the king of Egypt who lived between 245 – 204 BC:

''As one first came on board at the stern, there was set a vestibule open in front, but having a row of columns on the sides; in the part which faced the bow was built a fore-gate, constructed of ivory and the most expensive wood. Entering this, one came upon a kind of proscenium which in its construction had been roofed over. Matching the fore-gate, again, a second vestibule lay aft at the transverse side, and a portal with four doors led into it. On both sides, left and right, potholes were set beneath to provide good ventilation. Connected with these entrances was the largest cabin; it had a single row of columns all round, and could hold twenty couches. The most of it was made of split cedar and Milesian cypress; the surrounding doors, numbering twenty, had panels of fragrant cedar nicely glued together, with ornamentation in ivory. The decorative studs covering their surface, and the handles as well, were made of red copper, which had been gilded in the fire. As for the columns, their shafts were of cypress-wood, while the capitals, of the Corinthian order, were entirely covered with ivory and gold. The whole entablature was in gold; over it was affixed a frieze with striking figures in ivory, more than a foot and a half tall, mediocre in workmanship, to be sure, but remarkable in their lavish display. Over the dining-saloon was a beautiful coffered ceiling of Cyprus wood; the ornamentations on it were sculptured, with a surface of gilt. Next to this dining-saloon was a sleeping apartment with seven berths, adjoining which was a narrow passage-way running transversely from one side of the hold to the other, and dividing off the women's quarters. In the latter was a dining-saloon, with nine couches, which was similar to the large saloon in magnificence, and a sleeping-apartment with five berths.''

Teotihuacan’s Lost Kings, a television special, took an hour long look at the great city, its inhabitants, and the excavation of the Temple of Quetzalcoatl, (also known as the Feathered Serpent Pyramid.) The program revealed evidence of advanced engineering built into a tunnel system, and placed directly underneath the Pyramid.
