"Seals 835-839 present animals as their principal subjects. Although 835 has no parallel among Achaemenian designs, it is included here becasue the lions, in respect to their erect posture as well as the linerar treatment of their muscles, resemble the animals in contest scenes of the fully developed Achaemenian style. Though the arrangement of animals in tiered rows found in 836 is likewise unparallelled, the boars of this seal often appear in Achaemenian glyptic (831)."--Porada, CANES, p. 104
Four tiered rows of five walking boars each.
