"The cylinders of this group [900-908] contain a number of features distinctive of Cappadocian and of Syrian glyptic, besides some Mesopotamian elements, though the latter are less prominent here than in the Old Assyrian and in the provincial Babylonian group. ... The figure holding ball staff in 907 has parallels only in contemporary Cappadocian glyptic and in an Mitannian impression of later date (Nuzi 625)."--Porada, CANES, p. 114
