Geryon

Greek A monster with three heads, three bodies, and six hands. Geryon owned red cattle, which were guarded by the two-headed dog, Orthrus, and the herdsman, Eurytion. In his Tenth Labor, the hero Heracles slew the dog and the herdsman. After a fearsome battle, Heracles defeated Geryon. From Geryon's blood sprang a tree that produced a stoneless, cherrylike fruit that yielded a blood-red dye.
