What Turkic symbols? I already said that the Bulgar runes are much more closely related to the Sarmatian ones and are distanced both in time and space from the Orkhon script. The only Turkic relation that I can think of is that something similar to the IYI was the sign of the Kayi tribe, but that was both several centuries after the Bulgarians had stopped using the IYI and in a different region (Asia Minor – Caucasus, i.e. there’s no link between the two instances). It’s another matter that, just like the fake Tangra, the nationalists have adopted this symbol although its meaning is still rather unclear (most people think it’s a Pagan symbol for “Tangra” and the good old Pagan times, although it seems the symbol was actually used more often in Christian times, including in Christian context).
