Pithom also called Per-Atum or Heroöpolis or Heroonopolis was an ancient city of Egypt. Multiple references in ancient Greek, Roman, and Hebrew Bible sources exist for this city, but its exact location remains somewhat uncertain. A number of scholars identified it as the later archaeological site of Tell El Maskhuta. Others identified it as the earlier archaeological site of Tell El Retabeh.
The name
This name comes from Hebrew פיתום Pithom which was taken from the Late Egyptian name *Pi-ʔAtōm 'House of Atum'. Atum, a solar deity, was one of the major gods of ancient Egypt, and a sun-god of Heliopolis.
Biblical Pithom
Pithom is one of the cities which, according to Exodus, was built for the Pharaoh of the oppression by the forced labor of the Israelites. The other city was Ramses; and the Septuagint adds a third, "On, which is Heliopolis." These cities are called by a Hebrew term rendered in the Authorized Version "treasure cities" and in the Revised Version "store cities." The Septuagint renders it πόλεις ὀχυραί "strong cities." The same term is used of certain cities of King Solomon in I Kings 9:19.
Graeco-Roman Heroöpolis
Heroöpolis was a large city east of the Nile Delta, situated near the mouth of the Royal Canal which connected the Nile with the Red Sea. Although not immediately upon the coast, but nearly due north of the Bitter Lakes, Heroöpolis was of sufficient importance, as a trading station, to confer its name upon the arm of the Red Sea which runs up the Egyptian mainland as far as Arsinoë -- the modern Gulf of Suez. It was the capital of the 8th nome of Lower Egypt.
Location
Early on, the location of Pithom—just like the locations of other similar sites, such as Tanis—had been the subject of much conjecture and debate. The 10th century Jewish scholar, Saadia Gaon, identified the place in his Judeo-Arabic translation of the Pentateuch as Faiyum, southwest of Cairo. Édouard Naville and Flinders Petrie were looking for Pithom along the Wadi Tumilat, an arable strip of land serving as the ancient transit route between Egypt and Canaan across the Sinai—the biblical 'Way of Shur'. In the spring of 1883, Naville believed he had identified Pithom as the archaeological site Tell El Maskhuta. The site of Pithom, as identified by Naville, is at the eastern edge of Wadi Tumilat, south-west of Ismaïlia. Petrie agreed with this identification. John Holladay, a more recent investigator of the site, also supports this opinion.
Tell El Retaba
Eight miles west from Tell El Maskhuta is the site of Tell El Retabeh. This is approximately the midpoint of Wadi Tumilat. Here was found a group of granite statues representing Ramesses II, two inscriptions naming Pr-Itm, storehouses and bricks made without straw. So archeologists concluded that this was the site of Pi-Ramesses. The excavations carried on by Naville for the Egypt Exploration Fund uncovered a city wall, a ruined temple, and the remains of a series of brick buildings with very thick walls and consisting of rectangular chambers of various sizes, opening only at the top and without any entrances to one another. Some scholars, such as Manfred Bietak and Kenneth Kitchen, have argued that this was the ancient Pithom. This opinion goes back to the 19th century, when Alan Gardiner first identified Pithom with the site of Tell El Retaba, and this was later accepted by William F. Albright, and Kenneth Kitchen. Yet archeological excavations seem to show that Tell El Retaba had been unoccupied during the period when we find monuments relating to a town called Pithom. Naville identified all these locations as being in the region of Tjeku, the 8th Lower Egypt nome. The joint Polish-Slovak expedition has carried out a systematic research at Tell El Retaba since 2007. It is conducted with the cooperation of several institutions: Institute of ArchaeologyUniversity of Warsaw, the Polish Centre of Mediterranean Archaeology University of Warsaw, the Slovak Academy of Sciences and the Aigyptos Foundation. More recent analyses have demonstrated that the designation for the temple of Atum, pr-itm, can be found in inscriptions at both sites—both at Tell El Retaba and at Tell El Maskhuta. This seems to demonstrate that the name 'Pithom' was used originally for the earlier site, Tell El Retaba, before it was abandoned. And when the newer city of Tel El Maskhuta was built, the same name was applied to it as well – as the temple of Atum was moved to El Maskhuta. Thus, in effect, 'Pithom' was moved to a new location, which phenomenon is attested with some other cities as well, such as Migdol.
Wadi Tumilat Project
Modern excavations at Tel El Maskhuta were carried out by the University of Toronto 'Wadi Tumilat Project' under the direction of John Holladay. They worked over five seasons between 1978 and 1985. These excavations have shown that the history of Tel El Maskhuta is quite complex. There was a Middle Bronze IIB settlement there, associated with the Hyksos, followed by a long break until the late 7th century BC, when there was rebuilding. This construction at the end of the 7th century may have been carried out by Pharaoh Necho II, possibly as part of his uncompleted canal building project from the Nile to the Gulf of Suez.
