Note 869 — OMPHI,

I have shewn that people of old made use of caverns for places of worship: hence this at Athens had the name of Petra, or temple. [869]It is said of Ceres, that after she had wandered over the whole earth, she at last reposed herself upon a stone at Eleusis. They in like manner at Delphi shewed the petra, upon which the Sibyl Herophile at her first arrival sat [870]down. In short, there is in history of every oracular temple some legend about a stone; some reference to the word Petra. To clear this up, it is necessary to observe, that when the worship of the Sun was almost universal, this was one name of that Deity even among the Greeks. They called him Petor, and Petros; and his temple was styled Petra. This they oftentimes changed to λιθος; so little did they understand their own mythology. There were however some writers, who mentioned it as the name of the Sun, and were not totally ignorant of its meaning. This we may learn from the Scholiast upon Pindar. [871]Περι δε του Ἡλιου ὁι φυσικοι φασιν, ὡς λιθος καλειται ὁ Ἡλιος. Και Αναξαγορου γενομενον Ευριπιδην μαθητην, Πετρον ειρηκεναι τον Ἡλιον δια των προκειμενων.
