Shortly before the launch of the reconstructed Greek warship, Olympias, the first edition of The Athenian Trireme was published. Since then, five seasons of experimental trials have been conducted n the ship under oar and sail, and the lessons learned have been supplemented by new archaeological discoveries and research. For this second edition, there are nineteen new illustrations, including eleven photographs of Olympias at sea demonstrating features of her design that could be represented only by drawings in the first edition.
