Amazing Orthodox Christian Icon Theotokos the Unburnt Bush, Our Lady of the Burning Bush, Mother of God, Madonna.

The icon is based on the miracle witnessed by Moses in the Old Testament. In the book of Exodus, God calls Moses on Mt. Horeb from the midst of a bush which "was burning, yet it was not consumed." The Church sees the Unburnt Bush on Horeb as a type of the Most Holy Theotokos, who gave birth to Christ while still while remaining a virgin.
Most icons now depict the bush in a symbolic fashion with two overlapping diamonds. A red diamond represents fire, and a green diamond represents the bush. The two diamonds form an eight-pointed star with the Theotokos shown in the center.
The symbols of the four Evangelists: a man for St. Matthew, a lion for St. Mark, an ox for St. Luke, and an eagle for St. John, are in the four corners of the green diamond. These symbols are derived from Ezekiel 1:10 and Revelation 4:7. The red diamond has archangels depicted in its four corners.
