Adad-nirari III
They tell of "The treaty of King Bar-ga'yah of K[a]t[a]k, with Mati'el son of Attarsamak, king of Arpad." Some have identified this as the treaty of "Ashurnerari V" (Adad-nirari III or his son Tiglath-pileser III?) of Assyria and Matiilu (unknown) of Arpad (probably modern Tel Rifaat, Syria).
