Circular Relief Composition. The reliefs are cast in bronze, a material that darkens with time; the patina gives every face and fold of cloth its depth in the low sun. A close-up 360° view of the bronze reliefs, taken high on a pillar at golden hour. Georgian is written in its own alphabet, one of only a handful in the world; its three scripts — Asomtavruli, Nuskhuri and Mkhedruli — are on UNESCO’s heritage list.
