Leo the Deacon
Caloe was in the upper valley of the Küçük Menderes (Kaystros) in western Turkey, and is identified with the modern Kilis, Keles, Kelas, to the southwest of Alaşehir (ancient Philadelphia). The 10th-century historian Leo the Deacon, who was born in Caloe, describes the village as, "a very beautiful village in Asia, located on the slopes of Mt. Tmolos, near the sources of the river Kaystros, which, after flowing past the Kelbianon region and offering a most pleasant vista to the beholder, empties out into the gulf of Ephesos, that famous and celebrated city, and forms an estuary."
