Relief of a Baptism Scene. Among the Gospel scenes is the Baptism of Christ in the Jordan — a theme close to a nation that was baptised in the waters of the Mtkvari, by tradition, under King Mirian. A sacred scene from the memorial, with figures in long robes rendered in deep bronze relief. King Mirian III and Queen Nana accepted Christianity through Saint Nino, making Kartli one of the first kingdoms in the world to adopt it as the state faith.
