This is an image of a Russian saint called Иоа́нн Власатый — Ioann Vlasatuiy — “John the Hairy.” He is said to have that title because of the long and abundant hair on his head.
The abbreviated title inscription (with missing letters added) reads:
СВЯТЫ ИОАНН РОСТОВСКИЙ ЧУДОТВОРЕЦ МИЛОСТИВЫЙ
Svyatui Ioann Rostovskiy Chudotvorets Milostivuiy
Holy John of-Rostov Wonderworker Merciful
“Holy John of Rostov, Wonderworker, the Merciful”
The image is part of this larger 18th century Rostov icon showing scenes from his life as well as a Deisis at the top:
John is one of those saints called Блаженный — Blazhennuiy — “Blessed,” the title used for a юродивый — iurodivuiy/yurodivy — a “fool for Christ’s sake” — one of those fellows who behaved as though crazy, supposedly out of humility.
No one seems to know where John came from. He lived in Rostov during the reign of Ivan Groznuiy — “Ivan the Terrible” (1547-1584), and is thought to have been educated and to have known Latin, because he carried with him and read a Latin Psalter. It is supposed that he may have left Moscow to avoid all the troubles under Tsar Ivan, going to Rostov to live as a “holy fool.” John died on September 3, 1580, and there was a terrible storm during his funeral, with much thunder and lightning. The old stories say that many people who took sand from his grave and mixed it with water and drank it, or smeared it on their bodies, were healed by it.
John was supposedly named for another saint who is also called “John the Merciful,” but that would be the John who was Patriarch of Alexandria in the early 7th century, though he is said to have died in Cyprus. It is easy to distinguish him from John the Hairy by his bishop’s robe, his shorter hair, and his long, sharp grey beard.
We see this earlier John the Merciful’s title inscription at left and right, with a slightly different spelling in the abbreviation, but easily recognizable nonetheless. John’s scroll inscription is an excerpt from a prayer that the priest says quietly during the Liturgy of John Chrysostom:
Тебе предлагаем живот наш весь и надежду, Владыко Человеколюбче, и просим, и молим, и милися деем: [сподоби нас причаститися Небесных Твоих и Страшных Таин, сея священныя и духовныя Трапезы, с чистою совестию, во оставление грехов, в прощение согрешений, во общение Духа Святаго, в наследие Царствия Небеснаго, и дерзновение еже к Тебе, не в суд или во осуждение.]
We entrust to you, man-loving Master, our whole life and hope, and we
ask, pray, and entreat: [make us worthy to partake of your heavenly
and awesome mysteries from this holy and spiritual table with a
clean conscience; for the remission of sins, forgiveness of
transgressions, communion of the Holy Spirit, inheritance of the
Kingdom of Heaven, confidence before You, and not in judgment or
