Prokop Wiacki was a 17th-century orthodox saint known for his life as a holy fool. Born in 1578 near Khlynov (modern-day Kirov), he suffered mental impairment following a lightning strike in 1590. After being healed by Saint Tryphon at the Assumption Tryphon Monastery, he eventually embraced a life of wandering and holy folly. He is remembered for his prophetic abilities, which included foretelling illnesses, deaths, fires, and changes in taxation.
Life and ministry
Following his recovery, Prokop assisted Father Illarion at Saint Catherine's Church in Slobodskoy between 1595 and 1598. He later moved to Khlynov to live as a holy fool. During this period, he used his perceived spiritual insights to warn the local population about upcoming disasters or political shifts. He reportedly predicted his own death, which occurred in December 1627.
Veneration
The saint is commemorated within the orthodox tradition on December 21. He is buried in the Assumption Tryphon Monastery, located north of the cathedral. His reputation for prophecy and his ascetic lifestyle led the local community to honor him as a righteous holy fool.
