Ictis British tin was shipped from Massalia on the Mediterranean coast of Gaul. Julius Caesar, in his "De Bello Gallico", says of the Veneti: "This last-named people were by far the most powerful on the coast of Armorica: they had a large fleet plying between their own ports and Britain; they knew more about the handling of ships and the science of navigation than anyone else thereabouts." William Camden, the Elizabethan historian, took the view that the name "Ictis" was so similar to "Vectis", the Latin name for the Isle of Wight, that the two were probably the same island. The
Britain (place name) linguist Karl Schmidt states that the "name of the island was originally transmitted as Πρεττανία (with Π instead of Β) ... as is confirmed by its etymology". According to Barry Cunliffe: Following Julius Caesar's expeditions to the island in 55 and 54 BC, "Brit(t)an(n)ia" was predominantly used to refer simply to the island of Great Britain. After the Roman conquest under the Emperor Claudius in AD 43, it came to be used to refer to the Roman province of Britain (later two provinces), which at one stage consist of part of the island of Great Britain south of Hadrian's wall.
