Installations. The winepress (F2; Fig. 2) was rock-hewn and consisted of a shallow square treading floor, slanting slightly toward a square collecting vat. The excavation of the shaft (F3; diam. 0.4 m, depth in excess of 2 m), which was partly natural and partly hewn, was not completed. The basin was circular (diam. 0.5 m, depth c. 0.5 m) and rock-cut.
Flint Items. 2,639 flint items (c. 80% chips and chunks, and c. 20% flakes) were found on and between the rock steps. The assemblage included several blades (0.3%), cores and core trimming elements (c. 1%), tools and tool fragments (c. 1%). Noteworthy among the tools are the bi-facial axes and their fragments (60%), of a type that was widely used in the PPNA.
Evidence of Ancient Quarrying. Numerous cupmark-like depressions in different sizes were identified on the rock steps and along their edges (Fig. 3). Similar cupmarks were documented in nearby excavations (Grossman and Goren-Inbar 2010), and marks of quarrying flint chunks from the soft nari which is exposed on the surface were identified in them. The flint chunks were used to produce axes, which showed breaking patterns that indicate intensive use.
Installations devoid of any datable finds were exposed. Many similar winepresses were documented alongside hewn installations in the Modi‘in area (Spivak 2012, and see references therein), and in most instances it was not possible to date them or ascribe them to a specific settlement. Presumably, most of these winepresses were within the boundaries of the agricultural hinterland of the many ruins scattered along the rocky hills in the Modi‘in area (e.g. 'Ad 2011). Flint concentrations from the PPNA are common in the vicinity of Modi‘in (Spivak 2012, and see references therein). The most common lithic items in these assemblages are bifacial axes fashioned with transversal blows, a technique characteristic of the period. The tools were generally made of indigenous flint. The documentation of the quarrying marks and an analysis of their patterns contribute considerably to the research of the Early Neolithic period.
