Fictitious and Symbolic Creatures in Art, by John Vinycomb, [1909], at sacred-texts.com

Baphomet

A fictitious creature having two heads, male and female, the rest of the body female; said to be used as an idol or symbol by the Templars in their mysterious rites. The word is a corruption of Mahomet. Though mentioned in old works it does not now appear in British heraldry.
