However, the most famous Serbian medieval fresco is the "Myrrhbearers" (or the "White Angel") from the Mileševa monastery, painted in 1235, on the southern wall of the church. It depicts Archangel Gabriel sitting on Christ's grave. The identity of its author is unknown. In the 16th century, the "White Angel" was over-painted with another fresco, and so was hidden until the 20th century when the fresco was restored. This fresco was sent as a message in the first satellite broadcast signal from Europe to America after the Cuban Missile Crisis, as a symbol of peace and civilization. Later, the same signal, containing the White Angel, was transmitted to space in an attempt to communicate with extraterrestrial life forms.
