ABALUS was said by Pytheas to be an island in the northern ocean, upon which amber was washed by the waves, distant a day's sail from the aestuary called Mentonomon, on which the Gothones dwelt. This island was called Basilia by Timaeus, and Baltia by Xenophon of Lampsacus. It was probably a portion of the Prussian coast upon the Baltic. (Plin. Nat. 37.7. s. 11; Diod. 5.23; Ukert, Geographie, vol. ii. pt. 2. p. 33, seq.)
