The current survey was part of the excavation project undertaken along the separation fence south of Jerusalem. During the course of the project, the entire length of the water system was inspected in an attempt to examine phases and characteristics of its construction and quarrying; the storage pool and the covered channel that connects the pool to the hewn section of the spring were measured; another access shaft (the northern one) that was not mentioned in the previous surveys was identified, and a distinction was made between the system’s construction and use phases. 
In the course of the survey, the same hard limestone ‘stone lintel’ mentioned in the Marcus and Ben-Yosef report (supra), was found at the base of the southern shaft. The stone was identified as an architectural element of unusual dimensions that is carved as a capital in the Proto-Aeolic style. This element served as half of the monumental opening in the water system’s façade. This preliminary report provides a brief description of the architectural element, as well as other components of this unique water system, which contribute to its dating and understanding.
The element was partially buried at the base of the modern southern shaft (depth 3.6 m), dug into soil fill in a farming terrace layer. Its eastern side remained buried in the fill whereas its western side was only partially exposed; therefore, it full outline is not completely clear. Nonetheless, this seems to be a monumental element shaped like the Greek letter gamma (Γ). A decoration of a Proto-Aeolic capital with an excellent finish (Figs. 3, 4) is hewn on the upper part of the long front side (length 0.7 m, width 0.33–1.09 m, exposed height 1.36 m). Opposite, on the other side of the shaft, another element that was probably used in the other half of the opening was lying. Several shallow hewn depressions are visible on it, but this element is mostly buried beneath fill and its outline cannot be determined.
Differences were noted in the construction features of the covered channel segment. The section between the storage pool and the southern access shaft (length c. 25 m) is distinguished by haphazardly built walls of small fieldstones that were covered with large stone slabs. Two construction phases are evident in the segment of the covered channel located south of the southern shaft. In the later phase, the channel was made narrower by the construction of ashlars in secondary use. In the early phase, the construction is characterized by excellent quality building that utilizes large well-dressed ashlars (length up to 3 m). This section of the channel terminates at a retaining wall built of ashlars in secondary use. It seems that the wall was meant to support the tunnel’s ceiling after a collapse. A hewn room with a vaulted ceiling was discerned on the southern side of the wall. The rock-hewn section of the tunnel begins east of this room.
Twenty-four stone capitals decorated with a Proto-Aeolic design from the First Temple period are known from the main cities of the Kingdom of Israel: Samaria, Megiddo, Hazor and Dan. Eleven others are known from the Kingdom of Judea; ten capitals were found at Ramat Rahel where remains of a palace from the late eighth–early seventh centuries BCE were excavated, and one capital comes from the City of David excavations in Jerusalem (Lipschits 2009). Five capitals are known from the site of el-Mudeibi‘ – Mudaybi in Moab, and a capital was found in secondary use in the village of ‘Ain-Sara, west of Kerak, next to a spring of the same name. Two fragments of capitals are also known from the citadel in Amman (Lipschits 2009). The capitals from the Kingdom of Israel mainly date to the ninth century BCE and those from Judea and Jordan to the late eighth or early seventh centuries BCE. Although the central motif is identical, the capitals from the various sites differ in some features.
It is nowadays presumed that these capitals adorned gates and passages of public/government buildings (palaces). However, it should be mentioned that most of the capitals were not found in situ and hence, the question concerning their use arises (Shiloh 1979).
The element from ‘Ain Joweizeh is decorated with an equilateral triangle whose sides were carved in three parallel lines (length of inner triangle base 0.31 m, length of each side 0.39 m; length of outer frame base 0.56 m, length of each side 0.64–0.65 m). The triangle is set in an abacus (thickness 0.13 m), whose eastern half is broken. Concentric circles (oculus—diam. of outer circle 11 cm, diam. of inner circle 7 cm) adorn both sides of the triangle’s vertex and volutes flank its sides. Much of the eastern volute is missing. The outline of the western one is mostly preserved, although the surface of the stone and decoration are worn. An upper leaf was discerned between the western volute and the abacus and there might also be a lower leaf, although the condition of the element precludes ascertaining it. From an artistic standpoint the decorative characteristics of the architectural element from ‘Ain Joweizeh resemble the capitals found at Ramat Rahel, the City of David and el-Mudeibi‘ in Moab; however, its greatest similarity is to the capital discovered by Kenyon in the City of David excavations (Kenyon 1963).
The large size and great weight of the element and its being in the ‘seam’ between the late and early segments of the covered channel indicate that its current location is very close to the original one. On the basis of its decorative features and their comparisons from the nearby region, the element can be dated to the Iron Age in general, and the late eighth–early seventh centuries BCE in particular. The impressive wall segments surveyed in the section of the covered channel south of the southern shaft, the rock-hewn room and especially, the section of the rock-cut tunnel, reflect an enormous investment that allows attributing this system to a public project of national initiative. The hydrological knowledge and quarrying technology used in this project are known from various water systems throughout the country, which were dated to the Iron Age; the nearest one, both geographically and chronologically, is Hezekiah’s Tunnel in Jerusalem whose quarrying had been dated to the end of the eighth century BCE.
‘Ain Joweizeh spring is located c. 8 km from the City of David and c. 6.5 km from Ramat Rahel. A tunnel spring indicates the presence of a nearby settlement, yet the connection between the water works and its surroundings is still unclear. Many of the farming terraces in the vicinity of the spring are built of ashlars in secondary use. The soil used to fill the terraces has a grayish tinge reminiscent of “tell soil” and an especially large amount of potsherds from a variety of periods (Middle Bronze II, Iron Age, Roman and Byzantine) is scattered along the surface. There might have been an estate or royal palace similar to Ramat Rahel here during the eighth–seventh centuries BCE; another possibility is a settlement from this period that is mostly buried beneath the farming terraces covering the ravine. In any event, the site existing here benefited from the region’s abundant sources of water, its proximity to the road that ran through Nahal Refa’im and the ability to cultivate the agricultural areas in a broad section of the stream. The presence of a public/national(?) water system in the region from the time of the Kingdom of Judea has ramifications on our understanding of the agricultural hinterland surrounding Jerusalem, and the degree of administartive influence the city had over this region. This water system can contribute to the study of the technological and chronological aspects of the tunnel spring phenomenon that is characteristic of the mountain region. In the meantime, this is the only such spring that definitely dates to the Iron Age, although the possibility that this water system had an earlier phase cannot be ruled out.
