The tombstone of an Avar prince was discovered on Margaret-island in 1992. A runic inscription, written in the Yenissei Turk script and in Turkic language, can be read on it. Its text runs as follows: er atïm Kümüš ïnanč tudun. Ešim elim … ebim … ki(t)tim “My heroic name is Kümüš ïnanč tudun. I left my fellows, my people … my family (= I passed away)”. The inscription can be regarded as a decisive proof that the Avars spoke a Turkic language and that they came from the Yenissei region and had nothing to do with the Juan-juans.
