Francesco, thank you for your information. Online pictures of this place show its amazing beauty -- I only wish I could go there! As I do work in linguistics, its Greek name intrigues me, since "Piges" is not the classical name for "spring, fountain", namely "Pidax". Where could "Piges" come from??? I venture to say that it is a double corruption of the classical word "Pege".
Cl. Gr. "pEgE`" [pi, eta, gamma, eta] = Water in the sense of Running Water [as of rivers] and was so used, in the plural, by Homer, wherefore Pegai means Streams or the like. Now, I understand that Modern Greek preserves the word "pEgE" to mean "source; fountain"; however, in some locations, the first eta must have been pronounced and written as an iota, and the grammatical pluralization was made by analogy with other words, such as "pleiad-es" (the rainy sisters). So, you ended up with "epta PIGeS". (Please let me know if you have a better etymology.) // The ancient Dorians who made the island of Rhodes their home had "paga" instead of "pEgE", but obviously their word was not the basis the Mod. Gr. "Piges".
