Basilia
Basilia The island which Pytheas called Abalus, Timaeus called Basilia. (Plin. Nat. 37.7. s. 11.) It produced amber. On the other hand, the Baltia of Pytheas was the Basilia of Timaeus. Zeuss (p. 270) reasonably suggests that, although there is a confusion in the geography which cannot be satisfactorily unravelled, the word Basilia is the name of the present island Oesel.
