artist painted monumental The Dormition of the Virgin in Sopoćani monastery, which remained the supreme achievement of byzantine painting tradition. 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. Another notable mention is the fresco of Serbian queen Simonida, in Gračanica monastery, today located on the disputed territory of Kosovo. Born as Simonis Palaiologina, she was a daughter of the Byzantine Emperor Andronikos II Palaiologos (r. 1282–1328) and Irene of Montferrat, and the fourth wife of Serbian king Stefan Milutin (r. 1282–1321). Two celebrated Serbian poems were inspired by the beauty of the fresco. Two dark stains on the places where the queen's eyes were supposed to have created a common belief that her eyes were being carved out by Albanians, hence the well-known strophe by Milan Rakić: Your eyes were gouged out, oh beautiful image, On a pilaster at the approach of night, Knowing that no one would witness the pillage, An Albanian’s knife robbed you of your sight. However, between 1971 and 1976, during the conservation works in the monastery, it was discovered that for centuries the queen's eyes were lying under what actually was (unsuccessfully intentionally damaged) grey layer. Once the patches were removed, Simonida was shown to media with light-blue eyes. 16th and 17th centuries The Ottoman conquest of Serbia during the 15th century had a negative impact on the visual arts. The Serbs became part of the Rum Millet (Christian community), and were regarded as a lower class (rayah). The Serbian nobility was not integrated into the Ottoman state system, and the Ottoman government abolished the church. As the nobility and church were the main sources of patronage for architects and artists, the Early Modern period is considered an artistically less productive period in Serbian art.
