Facing ibexes rampant over tree

"The first four seals of the present group (586-589) are engraved in the style that prevailed in Assyria in the fourteenth century B.C. They show the same delicate modeling of the figures as the seals of that style, and a somewhat similar treatment of the space. It seems likely, therefore, that they date from the same time... Seals 586 and 587 each bear a lengthy inscription of the type mentioned above as characteristic of earlier Kassite seals. Moreover, 586 presents in its fish-men with flowing vases a theme that appears to be specifically Kassite, since it occurs in two Kassite seal designs and is not found on contemporaneous Middle Assyrian cylinders. Seal 587 has an Assyrian motif--a tree between two animals--but above this motif appears a row of rhombs that are typically Kassite." Porada, CANES, p. 66
