I have been reading the latest paper on Thracian by C. Brixhe (on the latest Handbook of Comparative and Historical Indo-European Linguistics) and I am really baffled by the conclusion.
In the 6th century this language is surprisingly close to Greek. And, since the particularly close relationship of Greek and Phrygian has been long since proven, it is not toward a prehistoric Thraco-Phrygian unity (cf. 3) that these new documents point. Rather, in the period between Proto-Indo-European and the emergence of Greek, Thracian, and Phrygian, it is probably necessary to posit a linguistic conglomerate to which the populations which were later to develop into Greeks, Phrygians, and Thracians belonged. They must have arrived in the Balkans in the same migratory wave at a period when they were linguistically still relatively undifferentiated (Brixhe 2006a: 141−142, 2006b: 57). From this it appears that Thracian may well not have belonged to the satem group of Indo-European languages (4).
I consider Brixhe a legendary linguist on the field of Greek dialectology, Phrygian and Thracian. However, it feels like the material found in Zone has not been assesed by anyone else (correct me if I'm wrong). There seems to be a number of inscriptions held behind locked doors and the only we get are some examples of dedications to Apollo and Bendis.
Can we have been so wrong about Thracian in the past? Considering that those new inscriptions come from the southmost part of what is called Thrace, is it possible that we are rather dealing with a different IE language, than what was spoken in the Bulgarian Thrace?
