Iolaos was the leader of Pelasgic bands, whom he conducted first into Libya and finally to Sardinia.
Similar relations prevail in the Balkan peninsula, where the Mediterranean stock is represented by the "Pelasgic" substratum.
Many have likewise asserted that the nations of the Epirus are Pelasgic, because the dominions of the Pelasgi extended so far.
The circumstances of the Pelasgic migration are differently related by the several historians, but the fact is asserted by all.
These settlements were made long before the Pelasgic migrations into Greece, which happened at least 2000 years before Christ.
