John of Tui

Saint John of Tui was a Portuguese hermit, born at Porto, who lived in the region of Tui in Galicia in the 9th century. All that is known is that from youth he wished to withdraw to a hermit's life and chose the region of Tui. After years of solitude and prayer he died at Tui and was buried in the Dominican convent.

His day is 24 June. He is no longer entered in the Martyrology of the Catholic Church, his veneration being allowed only locally. He was formerly very popular and much venerated, and was credited with protection against fevers. According to tradition, Queen Mafalda of Portugal placed the hermit's head in the church of San Salvador de Gandra (Penafiel), and part of the relic was taken to the chapel of the church of Nossa Senhora da Consolação in Porto. He is honored as a saint of the undivided Church, with a local cult.
