Gallikos (river)

The Gallikos (Γαλλικός), or Galliko river anciently known as the Echidorus (Ἐχείδωρος; Ἐχέδωρος), Cheidorus that empties itself into the Thermaic Gulf of the Aegean Sea within the western bounds of the modern city of Thessalonica before one reaches the larger and parallel Vardar river.

The name Gall-ikos also indicates the presence of Celts as Gall is the equivalent Greek word for the Latin Gaul and English Celt; who Herodotus claimed inhabited from this point back to the Bosporus and Hellespont, being the then Thracians. Smith believes the name changed due to the presence of the city of Gallicium "on the Roman road to Stobi".
