Sanesan was the king of Maskut in the early 4th century. He converted to Christianity, but then rejected it and slew Grigoris, the bishop who had introduced him to the faith. According to Faustus Byuzand, when Grigoris arrived in the Caucasian Albanian principality of Maskut (located along the northeastern Azerbaijani and south Dagestani shore of the Caspian Sea) to preach Christianity, its ruler Sanatruk (also known as Sanesan) of the local branch of Arsacides ordered him killed. Grigoris was trampled to death by mounted Maskut soldiers in the Vatnik Valley, near the present-day village of Nughdi 37 south of Derbent.
