Pontiff

A pontiff (from Latin pontifex) was, in Roman antiquity, a member of the most illustrious of the colleges of priests of the Roman religion, the College of Pontiffs. The term "pontiff" was later applied to any high or chief priest and, in Roman Catholic ecclesiastical usage, to a bishop and more particularly to the Bishop of Rome, the Pope or "Roman Pontiff".

Etymology

The English term derives through Old French pontif from Latin pontifex, a word commonly held to come from the Latin root words pons (bridge) + facere (to do, to make), and so to have the literal meaning of "bridge-builder". This may be only a folk etymology, but it may also recall antique tasks and magic rites associated with bridges.

Ancient Rome

There were four chief colleges of priests in ancient Rome, the most illustrious of which was that of the pontifices. The others were those of the augures, the quindecimviri sacris faciundis, and the epulones. The same person could be a member of more than one of these groups. Including the pontifex maximus, who was president of the college, there were originally three or fivepontifices, but the number increased over the centuries, finally becoming 16 under Julius Caesar. By the third century B.C., the pontiffs had assumed control of the state religious system.
