 The only known reference to this god so far in ancient literature is in Cicero's speech against Pizon, where he is mentioned under the name "Jovi Vrii" ("Iuppiter Urius").According to Cicero, Jupiter Urius had the most ancient and venerated of the barbarian temples, which was sacked by invading armies and resulted in diseases from which those afflicted never recovered.There is not enough information to draw clear conclusions about his cult, worship, or functions.
