Pelusium (Ancient Egyptian: ; /, romanized: , or , romanized: ; ; ; Arabic: ; Egyptian Arabic: ) was an important city in the eastern extremes of Egypt's Nile Delta, 30 km to the southeast of the modern Port Said. It became a Roman provincial capital and Metropolitan archbishopric and remained a multiple Catholic titular see and an Eastern Orthodox active archdiocese. Location Pelusium lay between the seaboard and the marshes of the Nile Delta, about two-and-a-half miles from the sea. The port was choked by sand as early as the first century BC, and the coastline has now advanced far beyond its ancient limits that the city, even in the third century AD, was at least four miles from the Mediterranean. The principal product of the neighbouring lands was flax, and the linum Pelusiacum (Pliny's Natural History xix. 1. s. 3) was both abundant and of a very fine quality. Pelusium was also known for being an early producer of beer, known as the Pelusian drink. Pelusium stood as a border-fortress, a place of great strength, on the frontier, protecting Egypt as regards to Syria and the sea. Thus, from its position, it was directly exposed to attack by any invaders of Egypt; it was often besieged, and several important battles were fought around its walls. Names and identity Pelusium was the easternmost major city of Lower Egypt, situated upon the easternmost bank of the Nile, the Ostium Pelusiacum, to which it gave its name. Pliny the Elder gives its location in relation to the frontier of Arabia: "At Ras Straki, 65 miles from Pelusium, is the frontier of Arabia. Then begins Idumaea, and Palestine at the point where the Serbonian Lake comes into view. This lake... is now an inconsiderate fen." The Roman name "Pelusium" was derived from the Greek name, and that from a translation of the Egyptian one. It was variously known as Sena and Per-Amun (Egyptian and Coptic: Peremoun) meaning House or Temple of the sun god Amun, Pelousion or Saien (), Sin () -Chaldaic and Hebrew-, Seyân (Aramaic), and Tell el-Farama (modern Egyptian Arabic). According to William Smith, it was the Sin of the Hebrew Bible (Ezekiel xxx. 15). Smith surmised that the word in its Egyptian and Greek forms (Peremoun or Peromi; Greek Πήλος Pelos) had the connotation of a 'city made of mud' (cf. omi, Coptic, "mud"). The anonymous author of the
