"Dating of 594 in the fourteenth century is indicated by its similarity to a seal impression of that time (Weber 316a). In each instance a decorative motif is formed by using the wings of the lion-griffins to frame a palmette tree. In the scene of the impression the shoulder feathers of the lion-griffin's wings are indicated by drillings. This distinctive detail (which appears to derive from Mitannian designs), though it is lacking in 594, does appear in 595." Porada, CANES, p. 68
