"In Kazan, in 1579, the nine-year old Matrona, whose parents' home had burned down in a fire, had a dream in which she beheld an icon of the Theotokos and heard a voice commanding her to recover this icon from the ashes of the ruined house. The icon was found wrapped in an old piece of cloth under the stove, where it may have been hidden during the Tartar invasions. The icon was finally brought to the Cathedral of the Annunciation of the Theotokos, where it became renowned for the healings that the Mother of God wrought through it for the blind... The icon of Kazan is one of the most beloved icons of the Mother of God in Russia." (Great Horologion)
