Arched Tree of Figures. The frescoes of Ateni Sioni and the gold of the Gelati mosaics show how much of Georgian history is told through images — just as it is here. A sacred scene from the memorial, with figures in long robes rendered in deep bronze relief. Niko Pirosmani, the self-taught painter of feasts and Tbilisi life, is another storyteller of the nation — Georgian art has always loved to narrate.
