some time in the 2nd millennium BC. There are however conflicting traditions and scholarly opinions identifying Ur Kasdim with the sites of Şanlıurfa, Urkesh, Urartu or Kutha. The biblical Ur is mentioned four times in the Torah or Hebrew Bible, with the distinction "of the Kasdim/Kasdin"—traditionally rendered in English as "Ur of the Chaldees". The Chaldeans had settled in the vicinity by around 850 BC, but were not extant anywhere in Mesopotamia during the 2nd millennium BC period when Abraham is traditionally held to have lived. The Chaldean dynasty did not rule Babylonia (and thus become the rulers of Ur) until the late 7th century BC, and held power only until the mid 6th century BC. The name is found in Genesis 11:28, Genesis 11:31, and Genesis 15:7. In Nehemiah 9:7, a single passage mentioning Ur is a paraphrase of Genesis. In March 2021, Pope Francis visited Ur during his journey through Iraq. Archaeology In 1625, the site was visited by Pietro Della Valle, who recorded the presence of ancient bricks stamped with strange symbols, cemented together with bitumen, as well as inscribed pieces of black marble that appeared to be seals. European archaeologists did not identify Tell el-Muqayyar as the site of Ur until Henry Rawlinson successfully deciphered some bricks from that location, brought to England by William Loftus in 1849. The site was first excavated in 1853 and 1854, on behalf of the British Museum and with instructions from the Foreign Office, by John George Taylor, British vice consul at Basra from 1851 to 1859. Taylor uncovered the Ziggurat of Ur and a structure with an arch later identified as part of the "Gate of Judgment". In the four corners of the ziggurat's top stage, Taylor found clay cylinders bearing an inscription of Nabonidus (Nabuna`id), the last king of Babylon (539 BC), closing with a prayer for his son Belshar-uzur (Bel-ŝarra-Uzur), the Belshazzar of the Book of Daniel. Evidence was found of prior restorations of the ziggurat by Ishme-Dagan of Isin and Shu-Sin of Ur, and by Kurigalzu, a Kassite king of Babylon in the 14th century BC. Nebuchadnezzar also claims to have rebuilt the temple. Taylor further excavated an interesting Babylonian building, not far from the temple, part of an ancient Babylonian necropolis. All about the city he found abundant remains of burials of later periods. Apparently, in later times, owing to its sanctity, Ur became a
