Revisiting Fara: Comparison of merged prospection results of diverse magnetometers with the earliest excavations in ancient Suruppak from 120 years ago

Ancient Suruppak, today Fara, was one of the major Sumerian cities in Mesopotamia. It was situated along one of the ancient watercourses of the Euphrates River. Findings date it back to the Jemdet Nasr period around 3000 bc with a continuous occupation until the end of the Ur III period around 2000 bc. Fara was first explored and excavated by the Deutsche Orient-Gesellschaft in the years 1902 and 1903 under the direction of Walter Andrae. Multiple excavation trenches with lengths up to 900 m transect the 1 km(2) wide mound and are still visible today which enables us to georeference the excavation maps. Today, the 2.2 km(2) wide archaeological area is dry and without any vegetation. Thousands of deep looting pits are covering the majority of mound which not only destroyed its upper metres but also challenge the application of geophysical prospection methods and their interpretation. The magnetometer prospecting of selected areas on and around the mound was carried out with three devices, two total field magnetometers and one gradiometer. The individual survey areas were combined in post-processing by applying a high-pass filter on the total field data sets and multiplying the vertical gradiometer data sets by a factor of two. This approach provides visually uniform magnetograms, despite being obtained by different devices, which simplifies subsequent visual interpretation. These magnetograms enable us to review, and to extend the results of the old excavations. The comparison show a good correlation in accuracy to the old drawings and positive identification of the already excavated features with magnetometry. Highlights of the survey are the discovery of the city wall confirming its existence, the layout of a unique building complex in the centre of the mound, likely a temple, traces of canals inside the city and an evaluation of magnetometer prospection over a looted area

Two Great Houses of Old Babylonian Ur

Visitors to the ruins of Ur venturing into the residential area south of the ziggurat and royal cemetery are confronted with a reconstructed “House of Abraham” (fig. 1), named after the city’s most famous putative resident. It is not clear who decided that this particular structure was the ancestral home of the patriarch, but it was certainly not Sir Leonard Woolley, who closed his celebrated excavations here in 1934. While he was convinced that this city was indeed the Ur of the Chaldees of the Bible—a claim that has not gone unchallenged—and even wrote a book postulating that the Old Babylonian houses here shed light on the origins of Yahwistic religion (Woolley 1936), he doubted that archaeology could ever link Abraham to a specific artifact or building. The massive brick structure one sees today was actually erected only two decades ago to promote tourism in anticipation of a papal visit that was delayed until March 2021. It was built on the ruins of half a dozen individual houses that Woolley had excavated in the area he called AH, generally following their ground plans but connecting the units with doorways to create a single edifice many times larger than any private residence of the early second millennium BCE (fig. 2). If the idea of naming this new creation after Abraham was to promote tourism, it has been a success: Among the thousands who visit Ur every spring, some even come to pray in these rooms, ignoring all warnings that the association with the family of Abraham is suspect

Revisiting Fara: Comparison of merged prospection results of diverse magnetometers with the earliest excavations in ancient Šuruppak from 120 years ago

Ancient Šuruppak, today Fara, was one of the major Sumerian cities in Mesopotamia. It was situated along one of the ancient watercourses of the Euphrates River.
