In 77 AD, Pliny the Elder mentions the Gutones as one of the peoples of Germania. He writes that the Gutones, Burgundiones, Varini, and Carini belong to the Vandili. Pliny classifies the Vandili as one of the five principal "German races", along with the coastal Ingvaeones, Istvaeones, Irminones, and Peucini. In an earlier chapter Pliny writes that the 4th century BC traveler Pytheas encountered a people called the "Guiones". Some scholars have equated these "Guiones" with the Gutones, but the authencity of the Pytheas account is uncertain.
