Although the sailing ship was coming more and more into favor because of the discoveries across the Atlantic, the galley was the man of war of this period. The dromons of the Eastern empire, with their stout build and two banks of oars, had given way to a long, narrow vessel with a single bank of oars which had been developed by men who lived on the shores of the sheltered lagoons of the Adriatic. The prime characteristic of this type was its mobility. For the pirate whose business it was to lie in wait and dash out on a merchantman, this quality of mobility--independence of wind and speed of movement--was of chief importance. Similarly, in order to combat the pirate it was necessary to possess the same characteristic. Of course, as in all the days of rowed ships, this freedom of movement was limited by the physical exhaustion of the rowers. In the ships of Greek and Roman days these men had some protection from the weapons of the enemy and from the weather, but in the 16th century galley, whether Turkish or Christian, they were chained naked to their benches day and night, with practically nothing to shelter them from the weather or from the weapons of an enemy. So frightful were the hardships of the life that the rowers were almost always captives, or felons who worked out their sentences on the rowers' bench. An important difference between the galley of this period and the earlier types of rowed ship is the fact that in the galley there was but one row of oars on a side, but these oars were very long and manned by four or five men apiece. A typical galley was about 180 feet over all with a beam of 19 feet and a depth of hold of about 7-1/2 feet. A single deck sloped from about the water line to a structure that ran fore and aft amidships, about six feet wide, which served as a gangway between forecastle and poop and gave access to the hold. The forecastle carried the main battery of guns, and was closed in below so as to provide quarters for the fighting men. The poop had a deck house and a smaller battery; this deck also was closed in, furnishing quarters for the officers. There were two or three masts, lateen rigged, adorned in peace or war with the greatest profusion of banners and streamers. Indeed huge sums of money were expended on the mere ornament of these war galleys, particularly in the elaborate carvings that adorned the stern and prow.
