The following miracles of St. Demetrios are translations from a 9th century text of Anastasius the Librarian. The current translation is from the Latin, as the Greek version is apparently lost. The text is taken from: http://www.ucc.ie/milmart/BHL2122.html. Also note, these miracles are by no means an artifact, but St. Demetrios continues to pour forth myrrh from his relics, and grants countless healings of soul and body throughout the world. For the life of St. Demetrios see: http://full-of-grace-and-truth.blogspot.com/2008/10/life-of-st-demetrios-myrrh-flowing.html and for a post on the Veneration of St. Demetrios and Thessaloniki, see: http://full-of-grace-and-truth.blogspot.com/2008/10/veneration-of-st-demetrios.html.
