It was known in Holland that the Mediterranean vessels were more pointed than ours, and a proof of it is found in the passage (p. 355) from van Yk’s well known work, where this author tells us that the special qualities of our ships as sailers was attributed to the greatly curved stern and hence to the full bow. And it is surely not uninteresting, then, to read further on (p. 85A) that the father of the author of the work, accompanied by his three sons, went to Genoa to build vessels able to advance even against the wind, something unknown until then in that city. Hence the art of tacking was not known at Genoa at that period, a manœuvre, furthermore, which the lateen sails did not allow. It was not until later that these sails were replaced by square sails. Hence it was not at all strange that ships with oars remained so long in use on the Mediterranean. On the other hand, it may be considered as proved that, from the earliest times, there existed broad vessels alongside of the long craft fitted with oars. (JAL, Glossaire nautique, p. 1049.)
Still, the few ancient boats which have been exhumed, seem to have reached such a high degree of perfection, that naval architecture must have attained a wonderful development even in the most distant ages. This should not surprise us, however, when we see the masterpieces left by the Mediterranean races, masterpieces which bear witness to their esthetic and practical sense.
As the progressive developments of the ship in the middle ages are studied and as the dimensions of docks and other installations among the Greeks and Romans are considered, it can be stated positively that giant ships were unknown to Antiquity and that the descriptions given thereof should be examined in the light of the conditions which dictated them to the author. Just, for example, as the importance of the city of Babylon, and the excavations made there show, it was singularly exaggerated by the ancient writers. Besides, do we not daily read communications about the extraordinary sizes of ships and engines, sizes which, after a little while, are surpassed by others still more extraordinary? And so will it ever be.
In conclusion, let it be said that the ancient models are still to be found in small wooden vessels and in fishing smacks. These models have come down through the course of the centuries without other changes than those wrought by the rudder and by decoration.
If then an exact idea of the types of the ships of the Ancients be desired, thorough investigations should be started so soon as possible in order to find them, to measure them and to make of them drawings with dimensions, as has been done for the Netherlands.
This rapid comparative study allows the mutual relations which exist between the nations to be established and to show that the ancient types special to Southern France, to Spain and to Portugal all belong to the Mediterranean family, that is to say: to the Southern centre.
