Philae
Philae (/ˈfaɪli/; Greek: Φιλαί, Arabic: فيله Egyptian Arabic: [fiːlæ], Egyptian pꜣ ı͗w q) is currently an island in the reservoir of the Aswan Low Dam downstream of the Aswan Dam and Lake Nasser, Egypt. Philae was originally located near the expansive First Cataract of the Nile in Upper Egypt and was the site of an Egyptian temple complex (...)
The most ancient was a temple for Isis, built in the reign of Nectanebo I during 380-362 BC, which was approached from the river through a double colonnade. Nekhtnebef was his ancient Egyptian royal titulary and he became the founding pharaoh of the Thirtieth and last native dynasty when he deposed and killed Nepherites II.
For the most part, the other ruins date from the Ptolemaic Kingdom, more especially with the reigns of Ptolemy II Philadelphus, Ptolemy V Epiphanes, and Ptolemy VI Philometor (282-145 BC), with many traces of Roman work in Philae dedicated to Ammon-Osiris.
