Near the headwater of the river Struma (stream from that Thracian word) in the Balkan mountains of southern Bulgaria (named for Bulgar a son of Togarmah) is the town of Vulcan, at the base of igneous mount Valcan, a rich ancient mining district where lived Pelasgians (Peleg a son of Heber) and Thracians (progeny of Tiras), the Pelasgians among whom some sojourned to Italy to become known there as the Etruscans (named for Tyrrhenus) who worshipped the god Vulcan, later adopted by the Romans.
