Somewhere in that mix, perhaps earlier were the Cynomolgi, "The Bitch Milkers" --if my non-study of Greek is correct. Is there anything concrete on these people.
****GK: I've not heard of them (but there's a lot I haven't heard of (:=)) Maybe you thought of the following? ->
(Strabo, 7.3.2 : "the poet [Homer GK]connected with the Mysi the "Hippemolgi" and "Galactophagi" and "Abii," who are indeed the wagon-dwelling Scythians and Sarmatians.
For at the present time these tribes, as well as the Bastarnian tribes, are mingled with the Thracians (more indeed with those outside the Ister, but also with those inside).
And mingled with them are also the Celtic tribes — the Boii, the Scordisci, and the Taurisci." *****
