Carpaccio, the great Venetian artist, whose period is covered by the dates 1450-1522, has left behind more pictures containing ships than any artist of his time. There is in one of his paintings a striking example of a contemporary Mediterranean warship. She is shown as having a mainmast with square sail and very small topsail. Aft she has both a mizzen-mast and bonaventure-mizzen, each carrying a lateen sail. She is fitted also with a small foresail, spritsail, and carries eight oars on each side.[53] Like Memling and other artists, Carpaccio utilises the celebrated story of “The Pilgrimage of St. Ursula,” for some of his best work. It is, indeed, owing to this story, necessitating the introduction of ships into the picture, that we possess much of our knowledge concerning mediæval craft. For instance, in “The Arrival of the Ambassadors,” in “The Return of the Ambassadors,” in “The Arrival at Cologne,” and “St. Ursula taking farewell of her parents,” we have presented many valuable details bearing on our subject of sailing ships. We see a small open boat in the first of these pictures. She has a tiller and one large single lateen sail, coming almost down to the water. In the background we see the big ship in which the ambassadors have travelled. She has a high poop, one mast and square mainsail. In the second picture we see a Mediterranean galley with her enormous sail. She still retains her name “trireme,” and it is remarkable how generally she continues to resemble her Roman ancestor. In the last of the four pictures mentioned above, we see a large ship resembling somewhat the caravel type.[54]
