Anvallus

Anvallus was a Gaulish god, known from several public inscriptions at Augustodunum (Autun).

[1][2] The title gutuater is typically understood to mean 'priest';[3] the gutuatres have at times been taken to be Romanized continuations of the druids.

[4] These altars were both discovered in 1900 on the site of Autun's railway station, along with a Greek-style helmet of thin bronze that would have been left there as a votive offering.

Lambert[8] and J.-P. Savignac,[9] this stone commemorated the dedication of a kind of seat or throne by a person named Licnos Contextos.

Lambert;[6] Delmarre gives the translation "Licnos Contextus dedicated to Anvalonnacos the (golden?)

One of the two Latin altars dedicated to Anvallus. The inscription [ 1 ] may be interpreted as "Consecrated to the august , to the god Anvallus, Norbaneius Thallus the gutuater [freely and deservedly fulfilled his vow]".
