The ram, the dolphin, the serpent, the tiger, the lion, the lynx, the panther, the ox, the goat and the ass are sacred to Liber Pater. Of these, only one seems to show up on the coins: the panther, according to common attribution. One myth tells of how Liber (or the Greek Dionysus or Bacchus) was captured by pirates who mistakenly thought he was the son of a rich king and intended to ransom him. He took the form of a panther, and the pirates leapt overboard and were turned into dolphins.
