The Vita Christi (Life of Christ), also known as the Speculum vitae Christi (Mirror of the Life of Christ) is the principal work of Ludolph of Saxony, completed in 1374. The book is not just a biography of Jesus, but also a history, a commentary borrowed from the Church Fathers, and a series of dogmatic and moral dissertations, spiritual instructions, meditations, and prayers. It was so popular in its time that it has been called a summa evangelica.
