This prefix is sometimes expressed with an aspirate, Phi: and as that word signifies a mouth, and in a more extensive signification, speech and language, it sometimes may cause a little uncertainty about the meaning. However, in most places it is sufficiently plain. Phaethon, a much mistaken personage, was an antient title of the Sun, a compound of Phi-Ath-On. Bacchus was called Phi-Anac by the Mysians, rendered by the poets [457]Phanac and Phanaces. Hanes was a title of the same Deity, equally reverenced of old, and compounded Ph' Hanes. It signified the fountain of light: and from it was derived Phanes of Egypt: also φαινω, φανεις, φανερος: and from Ph'ain On, Fanum. In short, these particles occur continually in words, which relate to religious rites, and the antient adoration of fire. They are generally joined to Ur, by which that element is denoted. From P'Ur Tor came Prætor and Prætorium, among the Romans: from P'Ur-Aith, Purathi and Puratheia among the Asiatics. From P'Ur-tan, πρυτανεις, and πρυτανεια among the Greeks of Hellas: in which Prutaneia there were of old sacred hearths, and a perpetual fire. The antient name of Latian Jupiter was P'ur, by length of time changed to Puer. He was the Deity of fire; and his ministers were styled Pueri: and because many of them were handsome youths selected for that office, Puer came at length to signify any young person. Some of the Romans would explain this title away, as if it referred to Jupiter's childhood: but the history of the place will shew that it had no such relation. It was a proper name, and retained particularly among the people of Præneste. They had undoubtedly been addicted to the rites of fire; for their city was said to have been built by Cæculus, the son of Vulcan, who was found in the midst of fire: [458] Vulcano genitum pecora inter agrestia Regem, Inventumque focis.
