Bacis
or PACIS, is only another name for the Egyptian Onuphis, the sacred bull, who was worshipped at Hermonthis in Upper Egypt, just as Apis was at Memphis.
In size Bacis was required to excel all other bulls, his hair to be bristly, and his colour to change every day. (
Macr. 1.21; Aelian,
Ael. NA 12.11.)
