From McKenzie et al. 2014, p. 209: "The bowl mentioned with the cross painted inside it (fig. 18.1, no. 1) is possibly the earliest sherd from the site. P. Bienkowski (pers. comm.) could not find an exact parallel for it but considered the shape, base, and ware very much like those of Iron II, whilst not having an exact parallel for the painted cross. However, early Nabataean pottery (Schmid's phase 1) does have painted crosses inside it, even if on smaller vessels (Schmid 2000: 27-28, figs. 73-76). This combination, i.e., a shape at least reminiscent of Iron II forms and a painted decor related to the earliest known painted decorations securely attributable to Nabataean pottery, could be one of the missing links looked for in recent research in order to bridge the gap between the end of the Edomite and the beginning of Nabataean material culture."
