This article suggests that the boar as a military standard is the totem animal of Ceres. This seems completely counter-intuitive from a numismatic standpoint. Whenever the Boar is associated with a deity on the coinage that deity is Hercules, A MUCH BETTER GOD to follow into battle than Ceres.

(I also don’t believe the a connection between the manheaded bull and the minotaur.)
