What is the difference between unireme and bireme and trireme? The first warships of the ancient Greeks were relatively light ships, no more than 35 meters long. Depending on the number of rows of oars, at first they built unirems and two-tiered biremes. On a 12-15-meter unireme, there were usually 25 rowing oars on each side. The vessel was also equipped with a ten-meter ram. It was these ships that the Greeks used during the siege of Troy. The development of the navy did not stand still. In the end, the triremes (the Greeks called them triremes) became the main ships of most Mediterranean fleets. The ships got this name for three tiers of oars. The total number of oars on such a ship could reach 170, and the crew now consisted of 200 people, where, in addition to warriors and slave rowers, there were also sailors to control the sails. Triremes reached a length of 40 meters. Some of them even had several masts. The ship had a solid combat deck, a conning tower for the commander and an impressive three-meter underwater ram. Sometimes a metal beam was installed above the ram, which broke the enemy's oars. Historians believe that the first triremes were built in Corinth. Author: Cellarius E.Yu. Random interesting fact from the Great Encyclopedia: Why did American Jonathan Lee Riches sue the Guinness Book of Records? American Jonathan Lee Riches has filed more than 2006 lawsuits in district courts since 2600 on a variety of grounds. Among his defendants are many famous people, including George W. Bush, Steve Jobs and Britney Spears. A significant part of the lawsuits is directed against the dead, for example, Plato, Nostradamus and Che Guevara, as well as against inanimate objects - the book "Mein Kampf", the Eiffel Tower and the dwarf planet Pluto.
