Syracusia (Greek: Συρακουσία, syrakousía, literally "of Syracuse") was a 110 m (360 ft) ancient Greek ship sometimes claimed to be the largest transport ship of antiquity. It only sailed once, from Syracuse in Sicily to Alexandria in the Ptolemaic Kingdom.
The Syracusia was designed by Archimedes and built around 240 BC by Archias of Corinth on the orders of Hieron II of Syracuse. The historian Moschion of Phaselis said that Syracusia could carry a cargo of some 1,600 to 1,800 tons and a capacity of 1942 passengers. It reputedly bore more than 200 soldiers, as well as a catapult. It sailed only once to berth in Alexandria, where it was later given to Ptolemy (Ptolemaios) III Euergetes of Egypt and renamed the Alexandria (Greek: Αλεξάνδρεια, literally "of Alexandria").
A discussion of this ship, as well as the complete text of Athenaeus (a late 2nd-century Greek writer who quotes a detailed description of the Syracusia from Moschion, an earlier, now lost, writer) is in Casson's Ships and Seamanship in the Ancient World.
Of particular interest in the discussion of the construction of the ship is the detailed description of the efforts taken to protect the hull from biofouling, including coating it with horsehair and pitch. This may be the first example of proactive antifouling technology (designed to prevent the attachment of fouling organisms, rather than to remove them).
Not much is known about the outside appearance of the ship, but Athenaeus describes that the top deck, which was wider than the rest of the ship, was supported by beautifully crafted wooden Atlases instead of simply wooden columns. Additionally, the top deck featured eight towers, equipped with two archers and four fully armed men. On the bow of the ship was a raised platform for fighting, on top of which was a giant catapult. 20 rows of oars would also have been visible from the outside, and possibly a promenade lined with flowers and tents for use by the passengers.
In terms of passenger comfort, the Syracusia would be the equivalent of the Titanic compared to other ships of the era. Its innovative design and sheer size allowed for the creation of various recreational spaces aboard, including a garden and an indoor swimming pool with hot water. The lower levels of the ship were reserved for the crew and the soldiers on board, while the upper levels were for the use of passengers. According to Athenaeus, the ship was beautifully decorated using materials such as ivory and marble, while all public spaces were floored with mosaics depicting the entire story of the Iliad. The ship was also equipped with a library, a drawing room and a gymnasium for use by the passengers, as well as a small temple dedicated to Aphrodite.
Ptolemy's son sought to outdo Syracusia. He ordered the construction of a huge warship - 423 feet high, 80 feet wide, bearing more than 4,000 oarsmen and 2,850 soldiers. However, according to Callixenus of Rhodes, it was an immobile ship.
