Bronze bull of Gallo-Roman age (I century B.C. – I century A.D.), discovered in 1861 near the village of Neuvy-en-Sullias, in the central region of France, now in the Historical and Archaeological Museum (Musée Historique et Archéologique de l'Orléanais), Orléans, France.
In Celtic tradition, the bull represented the strength and courage of the warrior, but also wealth and abundance. This last aspect is particularly emphasized in some Irish epic texts, like the Táin Bó Cuailnge (The Cattle Raid of Cooley), in which the raid, forming the central plot of the tale, was carried out by order of the queen Medb, who wanted to take possession of the brown bull Donn Cuailnge, in order that it could compete against the great white bull, Finnbenach, owned by her husband, the king Ailill. Both bulls were reincarnations of two pig keepers, always arguing and fighting with each other, and that at last they killed one another.
A divinatory ritual practiced in ancient Ireland, called tarbhfleis (“bull sleep”), consisted in wrapping a seer in the bloody hide of a just sacrificed bull. During the night, through his dreams, he could divine the identity of the next ruler of Tara, the sacred hill located in central Ireland, where the supreme king of the island resided (Monaghan 2004).
