Simonides of Ceos
Sophocles ("Antigone", 980–987), Aeschylus ("Agamemnon", 193; 651), Simonides of Ceos (Schol. on Apollonius Rhodius, 1. 121) and Callimachus ("Delian", [IV] 65) also placed Boreas in Thrace. Other ancient writers, however, believed the home of Boreas or the Riphean Mountains were in a different location. For example, Hecataeus of Miletus believed that the Riphean Mountains were adjacent to the Black Sea. Alternatively Pindar placed the home of Boreas, the Riphean Mountains and Hyperborea all near the Danube. Heraclides Ponticus and Antimachus in contrast identified the Riphean Mountains with the Alps, and the Hyperboreans as a Celtic tribe (perhaps the Helvetii) who lived just beyond them. Aristotle placed the Riphean mountains on the borders of Scythia, and Hyperborea further north. Hecataeus of Abdera and others believed Hyperborea was Britain (see below).
