Nikon the Dry was an eleventh-century monk of the Kiev Caves Monastery (the Kiev Pechersk Lavra) in Kievan Rus'. According to the tradition recorded in the synaxarion, he was the son of wealthy and illustrious parents but gave up his possessions to embrace the monastic life. He is commemorated on December 11, and his relics rest in the Near Caves of the Lavra.
The central episode of his life is his captivity. In 1096, during the incursions of Khan Bonyak, he was seized together with several other monks and enslaved by the Polovtsians, enduring harsh treatment for about three years. When he refused to be ransomed, his captors tormented him with hunger, exposed him to the summer heat and winter cold, and beat him; the tradition relates that they severed the tendons of his knees and ankles to prevent his escape.
By tradition his deliverance came through a vision: Saint Eustratius appeared to him and foretold his release, and Nikon told his captors that, through the prayers of Saints Anthony and Theodosius, the Lord would return him to his monastery within three days. On the third day, the synaxarion relates, he became invisible to his guards and was carried to Kiev, appearing among the brethren in the Dormition church during the Divine Liturgy. He was called "the Dry" on account of his severe fasting, by which his body was withered.
