[1] Buto, identified with Tell al-Fara'in ("Pharaohs' Mound") and the village of Ibtu or Abtu near the city of Desouk (Arabic: دسوق),[2] was an ancient city in the Nile Delta, even one of the oldest cities on earth, with a history back to the Neolithic age.
During the Roman and Byzantine era it became the seat of an early Christian bishopric.
During the Roman and Byzantine era there was a Bishopric based in the town of Buto, which was important enough in the Roman province of Aegyptus Primus to become one of the suffragans of its capital's Metropolitan, the Patriarchate of Alexandria.
Lequien's Oriens Christianus [3] identified Butus with Phthenothi, but according to Klaas A. Worp's list of Byzantine-era bishops in Egypt,[4] Ftenote is a different see [not titular], which had the bishops Pininute(s,) (325), Agapius (343) and Eracleius (451), in which case the first-mentioned wasn't bishop of Butus.
It is vacant since decades, having had a single incumbent, of the fitting Episcopal (lowest) rank:[6] The see remains a titular bishopric of the Coptic Orthodox Church of Alexandria.
