Simonov Monastery in Moscow was established in 1370 by monk Feodor, a nephew and disciple of St Sergius of Radonezh. It became one of the richest and most famous monastery, comprising six major churches, and many icons. Job became the abbot in 1571, and became the first patriarch in Russia in 1589.The monastery land formerly belonged to Simeon Khovrin, a boyar of Greek extraction and progenitor of the great clan of Golovins. He took monastic vows in the cloister under the name Simon; many of his descendants are also buried there. In 1379, the monastery was moved half a mile to the east. Its original location, where bodies of the warriors killed in the Battle of Kulikovo had been buried, is still commemorated by the old Simonov church.
During the 15th century, the cloister was the richest in Moscow. Among the learned monks who lived and worked there were Vassian Patrikeyev and Maximus the Greek.
