Thus Sitalces, son of Teres, King of the Thracians, and Perdiccas, son of Alexander, King of the Macedonians, became allies of Athens.

After taking Sollium, a town belonging to Corinth, and presenting the city and territory to the Acarnanians of Palaira, they stormed Astacus, expelled its tyrant Evarchus, and gained the place for their confederacy.

Cephallenia lies off Acarnania and Leucas, and consists of four states, the Paleans, Cranians, Samaeans, and Pronaeans.
