During August 2007, a trial excavation was conducted in the Sha‘ariya quarter in Petah Tiqwa (Permit No. A-5229; map ref. 190257–65/664914–22), prior to enlarging a building. The excavation, undertaken on behalf of the Israel Antiquities Authority and underwritten by R. Krisi, was directed by P. Spivak. Prior to the excavation, an archaeological survey was performed by M. Haiman and probe trenches were dug at the site.
An occupation level, several centimeters thick, was exposed beneath a layer of black soil (thickness 0.5 m). The level, slightly inclined to the north, was composed of a layer of yellow beach sand, gravel and body fragments of pottery vessels dating to the Hellenistic period. Below the occupation level was a layer of brown clay soil (0.20–0.25 m), which contained mixed fragments of bag-shaped jars from the Persian period, body fragments of amphorae, fish plates and jars from the Hellenistic period and a fragment of a Hasmonean lamp that dated to the reign of Alexander Jannaeus. Red hamra, devoid of any finds, was found below the clay soil layer. The finds from the excavation indicate that the area to the west of Nahal Mazor was occupied during the Persian and Hellenistic periods, including the Hasmonean era – periods which had not been previously documented in the region.
