Authenticity
A legend, which was first mentioned by Epiphanius of Salamis in the 4th century AD, purported that Mary may have spent the last years of her life in Ephesus. The Ephesians derived it from John's presence in the city, and Jesus’ instructions to John to take care of Mary after his death. Epiphanius however, pointed out that although the Bible mentions John leaving for Asia, it makes not mention of Mary going with him. The Eastern Orthodox Church tradition believes that Virgin Mary lived in the vicinity of Ephesus, where there is a place currently known as the House of the Virgin Mary and venerated by Catholics and Muslims, but argues that she only stayed there for a few years; this teaching is based on the writings of the Holy Fathers.
Although many Christians believe that no information about the end of Mary's life or her burial are provided in the New Testament accounts or early apocrypha, there are actually over 50 apocryphon about Mary's death (or other final fate). The 3rd century Book of John about the Dormition of Mary places her tomb in Gethsemene, as does the 4th century Treatise about the passing of the Blessed Virgin Mary.
The Breviarius of Jerusalem, a short text written in about AD 395, mentions in that valley the basilica of Holy Mary, which contains her sepulchre. Later, Saints Epiphanius of Salamis, Gregory of Tours, Isidore of Seville, Modest, Sophronius of Jerusalem, German of Constantinople, Andrew of Crete, John of Damascus talk about the tomb being in Jerusalem, and bear witness that this tradition was accepted by all the Churches of East and West.
