The terminal is engraved in two registers, the upper with a seated deity wearing a long flounced robe and a horned headdress, holding a rod and a ring; the lower register with a standing worshipper wearing a long robe, with a Kassite cross and scorpions in the field. The seven line inscription in Akkadian cuneiform reads (uncertain words in italics): "(God) Napirisha, great lord, faithful shepherd, the Mountain, May his (the king’s) scepter be blessed, may his progeny be lengthy! A prosperous reign of Anshan, and Susa, may he have his fill! of whatever his eye desires. Seal of Humbanumena, son of Attarkitah, King of Susa and Anshan, whose name from the womb of his mother Napirisha created (for kingship)."
There are very few inscriptions (two bricks and an agate votive) preserved from Humbanumena I’s reign, although his name is mentioned frequently in inscriptions of his son and successor (see p. 471 in. F. Malbran-Labat, “Elamite Royal Inscriptions,” in J. Álvarez-Mon, et al., eds., The Elamite World). For a similar deity holding a rod and ring, see the Middle Elamite cylinder seal in the Metropolitan Museum of Art, fig. 22 in E. Porada, The Art of Ancient Iran.
