According to Roman tradition, the head (caput) of the Etruscan hero Aulus Vibenna (olus), discovered when the foundation stone was laid for the Roman temple of Jupiter in the 6th cent. BC, prophesying the future greatness of Rome (Liv. 1,55,5; 5,54,7; Arnob. 6,7; Serv. Aen. 8,345). The historicity of an Aulus Vibenna from Vulci is evident in Etruscan and Latin inscriptions and grave paintings.
