Stephanos of Byzantium - Ethnika
Gea: a city near Petrai in Arabia, as per Glaukos in his Arabian Antiquities. The ethnonym is 'Geios'. In Petrai the personal name 'Gesios' is in local use. The celebrated sophist among physicians came from there, perhaps taking his name from the place. By analogy, the form should have been 'Geates' (as in 'Tegeates'). 'Geesios' seems to have existed earlier, as did 'Ithakesios', with 'Gesios' arising by contraction.
