Taurio Aithiopikoi, aka the Ethiopian Bull.
“THE TAUROI AITHIOPIKOI were a fabulous and extremely ferocious breed of bull native to Aithiopia (sub-Saharan Africa), whose red hides were believed to be impervious to weapons. They were probably derived from travellers’ accounts of the African buffalo.”
