The phrase Tajis of Mehmet refers to the Messianic Mithraists of Tachkastan who had been united to the proto-Karaites as Hagarim by Mehmet the Ishmaelite. The ethnonym "Taji" was pronounced "Tayi" by Afroasiatics and "Tazi" by Indoeuropeans. The word Mehmet is the Persian form of Mohmad, the Arabian Gnostic name for Jesus Patibilis.
