Jirov, Nikolai Fedorov
Nikolai Fedorov Jirov was a Russian historian who held the view that the Sumerians had migrated to the Balkans and unconvincingly put forward the Tartartia Tablets(a), found in Romania, as evidence of this. He was also the author of a 1967 book, Atlantis, in which he located Plato’s island in the Azores and he also wrote the preface to Roberto Pinotti’s book, Atlantide [509].
However, there is a persistent claim that the Sumerians are related to the Hungarians, located just north of the Balkans! (b)(c)(d)
