"I can not say I've heard that the Celts were seafarers, was a typical comment. Those who recall that Julius Caesar described the Britons mostly naked savages, with moments of iron only around their necks, (a torquetum or tanawa is an ancient sextant known to have existed in this period as Maui navigate a known Greek and was able to calculate the length.) times with the skin of a beast cast over the shoulders of the British think they have nothing better than a coracle man to cross water. Nothing could be further from the truth. In fact, most of Book III of Caesar's 'Bello Gallico' is devoted to the largest naval battle was once named to ride. And his opponents? Nothing less than the Celts of Brittany, whose fleet was increased by arrival of a flotilla that had summoned his allies in Britain! The combination of Gallic and British naval armament consists of immensely powerful force, numbering, so Caesar tells us, no less than 220 ships, larger than the construction and superior to those of the Roman armed opposition under Admiral Brutus. These Celtic ships, Caesar says, were of solid construction so that they can Outrider tempestuous or contrary winds in the ocean itself without damage ("De Bello Gallico ', books III, XIII, I). It is clear that these fine vessels, which towered over Roman galleys, had the capacity to cross the Atlantic Ocean "atque aperto Vasto Mari" in the large open sea ", as indicated by Caesar."
