Pontifex Maximus
According to legend, the first Pontifex Maximus was Numa Marcius, who was appointed by his friend, Numa Pompilius, the second King of Rome. No other "Pontifices Maximi" are mentioned in surviving sources until the overthrow of the Roman monarchy, traditionally occurring in 509 BC. Once appointed, the Pontifex Maximus held his position for life; a new Pontifex Maximus was normally appointed following his death.
