What is "phacusa"

Phacusa was a city in the late Roman province of Augustamnica Prima. It served as a bishopric that was a suffragan of Pelusium, the metropolitan see of that province.

Ptolemy makes it the suffragan of the nomos of Arabia in Lower Egypt; Strabo places Phacusa at the beginning of the canal which empties into the Red Sea; it is described also by Peutinger's Table under the name of Phacussi, and by the Anonymus of Ravenna (130), under Phagusa.

Phacusa is identified widely with the modern Tell-Fakus; Heinrich Brugsch and Edouard Naville place it at Saft el-Hinna, about twelve miles from there.

Phacusa is a genus of moths in the family Zygaenidae.
