An antique Russian Orthodox hand painted icon entailed Most Holy Theotokos the Unburnt Bush, commonly called the Unburnt Bush Icon. This depiction of the Virgin Mary is based on the miracle witnessed by Moses on Mount Horeb, as narrated in the book of Exodus: God calls Moses, while on Horeb, from a bush which was burning, yet it was not consumed. Tempera and gold on a wooden panel. The icon represents the bush and the flame symbolically, as two overlapping diamonds: a green one representing the bush, and a red one representing the flames. They both form an eight-pointed star with the Theotokos in the center holding the Child. Dates to the 18th century. Antique Russian Orthodox Icons And Religious Collectibles.
