Nicholas of Tolentino, known as the Patron of Holy Souls, was an Italian saint and mystic. He is particularly invoked as an advocate for the souls in Purgatory, especially during Lent and the month of November. In many Augustinian churches, there are weekly devotions to St Nicholas on behalf of the suffering souls. November 2, All Souls' Day, holds special significance for the devotees of St. Nicholas of Tolentino.
