Yesterday we wondered about what identified a particular ring as being a 'gladiator ring', which led to some useful commentary by SM in our forum ... today we have another (from the same seller), though, which is doubly mysterious as being identified as a gladiator ring and, we are told, bearing an image of Sol Invictus; actually, it's triply mysterious because it's also claimed to be "Early Christian". Looks like a ring with an X in a box to me.
