There is not much information on Cyril and his deeds. In 1566, Cyril was appointed
archmandrite at the
Troitse-Sergiyeva Lavra. On 11 November 1568, he was elected
metropolitan in favor of the recently deposed
Metropolitan Philip. During Cyril's term,
Ivan the Terrible's fierceness reached its climax. In 1571, a
Crimean khan
Devlet I Giray attacked
Moscow and ravaged the city. Metropolitan Cyril had to hide in the
Cathedral of the Dormition in the
Moscow Kremlin to avoid death. It was Cyril who had asked Ivan IV not to execute Ivan Mstislavsky, accused of bringing the
Tatars to the capital. Metropolitan Cyril died on 8 February 1572, and was interred at the Novinsky Monastery. ==References==
