In addition to the Codex Athous Dionysiou and the Icon of the Hodegetria, Mount Athos houses numerous other treasures. For instance, the Icon of the Virgin Mary, believed to be one of the world's oldest icons and attributed to Saint Luke the Evangelist, is housed at the Vatopedi Monastery. Another notable treasure is the Codex Sinaiticus, one of the oldest and most complete copies of the Bible, housed at the Library of the Great Lavra Monastery, the oldest monastery on Mount Athos.
