Although shipbuilding proper comes with the Metallic Age, we must not assume that the change was made universally or at once. The transition would be made rapidly or but slowly in proportion as the tribe or nation were enthusiastically maritime or otherwise. In some parts of Europe the skin-boat or even the dug-out would be in use, while other shores were seeing built vessels of planks and ribs. The first historic account that we possess of these more modern vessels is to be found in Cæsar’s account of the Naval Campaign against the Veneti in the year 54 B.C. From this narrative we learn that the ships of the Veneti were somewhat flatter than those of the Romans, so that they could more easily encounter the shallows and ebbing of the tide.[32] The prows, we are told, were raised very high, and the sterns likewise—“proræ admodum erectæ atque item puppes”—so that they were suited for the force of the waves and storms which they had been constructed to sustain. We have, then, here a new design in naval architecture recorded—the Viking type of ship—although it had been in existence for a considerable time in the North. The high prows and sterns would immediately impress those who had come from the more peaceful waters of Italy. Further it is said that these ships were built of oak throughout and designed to be enormously strong. The crossbeams, made of logs a foot thick, were fastened by iron spikes as thick as a man’s thumb. The anchors were made fast by iron chains instead of cables, while their sails were made of skin and dressed leather. These were used because they lacked canvas or the knowledge to apply it to such a use, or more probably because they thought canvas would be of too little strength to endure the tempests of the ocean and violent gales of wind, and that ships of such great burden could not be managed by them. Perhaps in the use of hides for sails, we have the parent of the practice of using tanned sails so common in our fishing fleet and barges. The relative character of the two kinds of ships Cæsar points out, as we mentioned earlier in the chapter, was that the Roman fleet excelled in speed alone and in oarsmanship. Otherwise the ships of the Veneti were, considering the nature of the place, and the violence of the storms more suitable and better adapted on their side. Nor could the Roman ships injure severely the ships of the Veneti by means of their beaks, so strong were they. And further, so high were these ships that the Romans found great difficulty in hurling weapons at them. Whenever a storm arose and the ships of the Veneti ran before the wind, they could weather it more readily and heave-to safely in the shallows, and when left by the tide feared nothing from rocks and shelves, for—“the risk of all such things,” ends the account pathetically, “was much to be dreaded by our ships.”
