St. John, Igumen of Raithu Monastery
Forms of name: John
Contemporary of St. John Climacus. It was in obedience to a request from St. John of Raithu that St. John Climacus wrote The Ladder of Divine Ascent.
St. Martyrius of Sinai
Forms of name: Martyrius
Recognition uncertain. Spiritual father of St. John Climacus. I am assuming his sainthood because, while he is not listed in any compilations of saints that I've seen, when he appears in the icons of St. John Climacus he is depicted with a saints' halo.
