He is also known from various seals, one of them in which his name was formerly read "Tarkondemos".[1] This is a bilingual seal, combining a cuneiform inscription on the rim and the corresponding Hittite hieroglyphs around the figure in royal dress, giving the name of the ruler: Tarkasnawa.[1] This bilingual inscription provided the first clues for deciphering Hittite hieroglyphs.
