Archaeologist Michael Fuller, who has worked at Dura Europos, has been collecting photographs of Mithraic monuments. He modestly writes to say:
Here are a few of my webpages with images of Mithraic reliefs, altars, etc… Most of these duplicate images you already have, but a few maybe new to you.
You are welcome to add any of my images to your data base as long as I am given credit. I am pretty sure that I have some more images of Mithraic reliefs and will look. I might also be able to track down images of the lamps from the Dura mithraeum.
I shall be delighted to make use of some of these, and it is a very generous offer.
