Listen while I tell you just what the riddle is. That stone is a beryl, in general not a particularly rare mineral, although blue-green beryls of such pure water are rare enough; they are found in South Africa and nowhere else in the world. That’s the first point. The carving on the stone is a cameo and ornaments of this type were greatly admired in Greece when ancient Hellenic art was at its best. Now the beryl is a very hard stone and such a carving could only have been made with a diamond which the Greek sculptors did not have. That’s the second point. Next, take the three male figures — the central one is undoubtedly a Negro, the one on the right a Hellene, and that on the left, one of the Mediterranean peoples, probably a Cretan or an Etruscan. Lastly, the quality and technique indicate that the work belongs to the most flourishing period in the history of Greece; nevertheless there are a number of features that show that it was made at a much earlier date. And then, the spears are of a peculiar shape unknown in either Greece or Egypt… So you see there are several contradictions, a number of incompatible indicants… but despite them the cameo exists, it’s before your eyes…”

The archaeologist paused and then continued in the same abrupt way:

“There are many more historical riddles. All of them tell us one thing: how little we know. We have very little knowledge of how the ancient peoples lived. Amongst the Scythian works of art in our gold repository, for example, we have a gold buckle. It is two thousand six hundred years old and carries the image of the extinct sabre-toothed tiger in all its details. Yes, yes, and the palaeontologists will tell you that the sabre-toothed tiger became extinct three hundred thousand years ago… Ha! And in Egyptian tombs you will see frescoes on which every kind of animal found in Egypt is drawn with amazing accuracy.
