What remains is typically just pebbles, rocks and bits of modern refuse, but the dirt is also peppered with bits of antiquity. The objects are cleaned, photographed, digitized, cataloged, and sent to a Jerusalem lab where the senior staff, headed by Barkay and Professor Zachi Dvira.This is a very thorough article, which covers the background of the project, its funding, its accomplishments, and its critics. Read it all.
Most of the tens of thousands of items found in the pans by volunteers are small — an abundance of coins, innumerable fragments of clay, figurines, brightly colored mosaic tiles and beads, arrowheads, inscribed stones and bits of bone. In explaining the trove of tiny artifacts found, Barkay made regular reference to biblical and post-biblical characters in corresponding the items to time periods: clay figurines smashed during the time of the just kings of Judah, seal impressions with the names of priests mentioned in the book of Jeremiah and coins minted during the rein of King Antiochus IV Epiphanes, who fought the Maccabees. The relics catalog the history of Jerusalem from antiquity through the modern era, he explained.
Other finds include rare coins, like a half-shekel minted in the first year of the Great Jewish Revolt against Rome in 66 CE; a seal impression left in clay, from the 6th century BCE bearing the name of a Judean official; and golden mosaic tiles from the early Islamic period which once decorated the Dome of the Rock’s exterior before it was renovated.
“Our main method of dating is via typology,” Barkay said. “We try to find parallel, similar objects found elsewhere in context” and use them to date objects found in the Temple Mount fill.
“That is one of the axiomatic assumptions of archaeology,” he explained, “that there is a fashion in human life, and objects of the same time looked similar here in the Temple Mount and elsewhere.” Unfortunately, the project presently lacks the necessary funds to perform radiocarbon dating on organic matter such as fox, cow, sheep, and pig bones to better date some of the finds.
“It is true that we are dealing with material that has no context. We do not know from what depth the material came. We do not know what was found next to what, with what structures are they associated,” Barkay said. He noted, however, that there had previously been no archaeological survey of the Temple Mount, calling it “an archaeological black hole” comprising one-sixth of the Old City.
Since King Herod built the platform surmounting the Temple Mount in the first century BCE, it has been “a closed box,” which “didn’t have large-scale earthen works carried out, so no earth was brought in and no large quantities were taken out. The soil is indigenous,” Barkay said.
