Julius Caesar discusses the role of the vergobret several times in his Commentaries on the Gallic War, referring to the office with the terms princeps civitatis, principatus, and magistratus.

One of the rare archaeological testaments of the vergobret comes from the 1978 excavations of Dr. Allain in the zone of the temples to Argentomagus (Saint-Marcel, Indre), where an olla of terra nigra, engraved after being fired, bears the inscription, "vercobretos readdas".
