The print magazine article itself has some good photographs of human remains in situ.
>the archaeological evidence for a large Galatian presence at the site was not overwhelming until our discovery of grisly evidence of rituals involving humans. The broken-necked bodies and decapitated heads at Gordion cannot be attributed to any local Anatolian group, but are characteristic of European Celts.
I can hardly believe the shabby logic in this excerpt. IOW, this has to be a Celtic site because Celts do what we think was done here, and to whom we think it was done, and for the reasons we think.
Excuse me???? Is this the genius on which modern archeology is built?
