When working on Osprey books that cover older periods, it can often be difficult to separate fact from fiction. Chronicles are often incomplete, contradictory, or obscure. But what do you do, when numerous chronicles, written by different people, at different times, all tell a similar story of a miraculous event?
Luckily, this problem doesn\'t come up very often. But in Fortress 25: The Walls of Constantinople AD 324 - 1453 it led author Stephen Turnbull and artist Peter Dennis to create the only Osprey plate to contain a vision of the Virgin Mary.
Whether or not you believe in such miracles, it is obvious that the citizens and defenders of Constantinople certainly did. And it sure makes a nice piece of art.
