Pacis or Bacchis (Greek) Bakha (Egyptian) The sacred bull of Hermonthis. Although not so celebrated as Apis and Mnevis, he was styled the bull of the Mountain of the Sunrise (Bakhau), and the lion of the Mountain of the Sunset. Like Mnevis he was depicted with the solar disk between his horns, the reference being not to the cosmic energy of the spatial Deeps represented by Mnevis, nor to the lunar energy represented by Apis, but to the opening (sunrise) and the closing (sunset) of the solar system.
