The shipbuilding of large war - ships
(210 B.C)




The ancestors of the Great Alexander started an, without limits, competition for the building of gigantic war - ships. So they created a brilliant shipbuilding tradition, that remained in the Greek navy's history. Those ships were huge in both, size and set of oars, therefore they became useless after a while (because the inconvenient of their size). However for 300 - 400 years they succeeded in changing the scenery of this era, they improved the art of shipbuilding and they gave a new form to the war – conflicts in sea.

In 315 B.C, Antigonos built a ship with a seven – sequence of oars. His son, Dimitrios the besieger, in 301 B.C, ordered the construction of a thirteen-reme (a ship with a thirteen-sequence of oars), a ship with fifteen-sequence of oars and one with sixteen-sequence of oars. The first Ptolemians imitated them and they built two thirteen-remes and Lisimahos built a sixteen-reme. Ptolemaios the II built a twenty-reme ( a ship with twenty-sequence of oars) and two thirteen-remes , however Ptolemaios the V built a forty-reme (a ship with forty-sequence of oars).

When we say “ sixteen-reme or thirty-reme we don’t mean sixteen or thirty-sequence of oars in layers, the one up on the other. Practically in a trireme the oars are in parallel position, from that point and further we refer to the people who rows. For instance with the term “sixteen-reme” would probably meant that sixteen people uses an oar or the two parallel oars or that a group of oars in vertical position (ex. Of three rows) are used by sixteen rowers (8 on the up-level, 5 in th middle and 3 in the lower level).

For those super – constructions a grade role played the advance in the war – tactics with the catapults e.t.c. Therefore they constructed like-catamaran ships with two hulls joined with thousands rowers (4000), 128m length and many warriors (2850 soldiers). However, because of their low speed and their large shape and cost they became useless, after a while.

Greek Brireme from the period of the Trojan War 1250 BCE

Model of Greek Bireme of the Trojan War 1250 B.C. from Hobby World Of Montreal


The Bireme was the warship used at the time of the Trojan wars. It had a broad bottom with a shallow draft. Biremes were propelled by two banks of oars and virtually skimmed over the seas. The bow had a portion that protruded out at water level. It is thought that this configuration was intended for ramming and piercing the enemy's ships hull.

This earlier configuration is close to the structure of the boats used by the Greeks to defeat the Persian fleet at Salamis in 480 BCE. It is clear from ancient Iconography that the evolution and changes to the configuration of these ships evolved over an extended period of time. The time between the Trojan and Persian wars being approximately 800 years.

Greek Bireme circa 500BCE

An important version of an ancient warship was the "bireme" equipped with an outrigger. The advantage was, that this way, a ship could have two rows of oars on each side. The upper row of oars-men was sitting on an upper bench more outside, so their oars wouldn't interfere with the oars of their fellow mates sitting below. A "bireme" could be equipped with as many as a hundred oars-men, fifty on each side of the ship.

The next step in the evolution of Greek war ships was the creation of the "trireme" with three rows of oars-men on each side of the ship (seethe modern recreation above). The "trireme" was the standard warship of most Greek city-states. While a "trireme" still had a quite narrow hull, the outrigger had to be wider than on a "bireme". Most Greek "triremes" had a partial fighting-deck, while the later Roman version of this warship-type, had a full deck. The ship shown is a recreation made by the Trireme Trust.
