To all the church history buffs (because I don't have time to track it down for myself!): I've found it common for Eastern Orthodox (and others, sometimes) to claim that Luke created the first "icon" of Mary with Jesus. One or two articles claimed that this tradition was alluded to in some early church writings, including Esubius' history of the church. Any idea how/when this belief came into being, how widely it may have been believed, and whether there is any factual basis for it? Obviously uncovering factual basis for anything that old can be a challenge. Apparently though, iconography does show up pretty early in history, although from what little I've read, icons weren't widely used in public worship until the 4th or 5th century.
