Janus the Dual Faced God
Janus was known as the Dual Face god in ancient Roman mythology. He was the god of beginnings, endings, time and transitions. He is usually depicted as having two faces as he looks to the past and the future. He was worshipped at the beginning of harvest and planting times. Janus was also celebrated at marriages, deaths and other beginnings such as birth that occurred throughout daily life. Janus the Dual Faced god was the symbol of change for the journey from the past to the future and young peoples’ growth to adulthood. He also presided over the beginning and ending of conflict, war and peace. The doors of his temple were kept open in time of war and closed during peace time. It had been thought that January was named for the dual face god Janus but ancient Roman farmers almanacs say this honour goes to Juno who was the guardian deity of the month.
The most famous two faced comic supervillain is Harvey “Two-Face” Dent. Appearing in American comic books (published by DC Comics), he is most commonly depicted as an adversary of the superhero Batman. He is one of Batman’s most persistent enemies and a prime member of Batman’s Rogues Gallery.
Wikipedia says of him “once an upstanding district attorney of Gotham City and an ally of Batman, Harvey Dent goes insane after a mob boss throws acid at him during a trial, hideously scarring the left side of his face. He adopts the "Two-Face" persona and becomes a criminal, choosing to bring about good or evil based upon the outcome of a coin flip.
