A number of important commercial port cities of the Greek waters were dedicated to Achilles. Herodotus, Pliny the Elder and Strabo reported on the existence of a town "Achílleion" (Ἀχίλλειον), built by settlers from Mytilene in the sixth century BC, close to the hero's presumed burial mound in the Troad. Later attestations point to an "Achílleion" in Messenia (according to Stephanus Byzantinus) and an "Achílleios" (Ἀχίλλειος) in Laconia. Nicolae Densuşianu recognized a connection to Achilles in the names of Aquileia and of the northern arm of the Danube delta, called Chilia (presumably from an older "Achileii"), though his conclusion, that Leuce had sovereign rights over the Black Sea, evokes modern rather than archaic sea-law.
