=== The three corners of Britain: Kantion, Belerion and Orkas ===
Opposite Europe in Diodorus is the promontory (''akrōtērion'') of ''Kantion'' ([[Kent]]), 100 stadia, about {{convert|11|miles}}, from the land, but the text is ambiguous: "the land" could be either Britain or the continent. Four days' sail beyond that is another promontory, ''Belerion'', which can only be [[Cornwall]], as Diodorus is describing the triangular perimeter and the third point is ''Orkas'', presumably the main island of the [[Orkney]] Islands.
