Etruscan Janus from Vulci, 2nd C. BCE

"The Vulci were a tribe or people who gave their name to their city and were one of the legendary twelve peoples of Etruscan civilization who later formed the dodecapolis Etruscan League to protect their interests.

Although the wealth, magnificence and population of Vulci must have been among the first of Etruscan cities, it is mentioned only rarely in ancient literature or potential texts for some periods have been lost; hence the history of Vulci may be reconstructed mainly from archaeology."
