A great picture. However, unfortunately it cannot contain its fascinating history, from its foundation by Peloponnesian people. (They were distant cousins of mine, for they founed my ancestral city, Thoyrioi in South Italy, named after the Peloponnesian Thouria.) Recently the name "Ialyssos" has intrigued me because it has seemed to be a theophoric name (a name that contains the word "god" or the name of a god), like the well known Japetos, the titan who was cast down by the Olympian gods. So, I see Japetos as Ja/Ia/Ya + petos, that is, the "Ya cast down One." So, I see Ialyssos as Ya-lyssos. Let us remember that Mount Parnassus is in the Peloponnese and that one of its peaks [where a god resides] was called YampeiE. From various linguistic evidence I have inferred that Ya was the rain-god, whereas Zeus was the storm-god.
