Roxolani and Iaziges

[Alanus]

Back to you, Childeric

I respected the late Janos Harmatta for his diligent and singular work on the "blending" of the Iazyges and Roxolani upon the Hungarian Steppe, thereafter referred by period Roman authors as the "Sarmatians." (Not a totally accurate definition). I think the various tribal associations you listed might be accurate, but (in total) it's not my field. The Taifali rode as the Tyrfingi Goth's cavalry for over 150 years, finally breaking from them when Athanaric got a bug up his ass about some trivial dispute and banned them from a (failed) redoubt he was constructing to ward off the Huns.

The Iazyges probably did use archery to some extent, and you're correct in they had no horse armor and wore light armor themselves. This may have changed to heavier personal armor after their affiliation with the Roxolani, but I don't believe they ever fielded a Roxolani-styled cataphract.

Sorry I can't be of more help, but my main interest lies earlier in the far East with the Altaic Cultures, the pre Yue-chi association with the Chinese, the late Saka, Wusun, and Kangju, and the final formation of the new confederation eventually known to the Romans as the Alans. This is the culture that bred the Akhal-teke conformation horse, known to the Han as "Heavenly" and "Blood-Sweating" Horses. Also, this is the beginning of the Late Sarmatian Period that would produce the two-handed "Late Sarmatian Type 1 Sword" as used by the early Alans-- the Aorsi, Sirakes, and Roxolani. This is When it All Happened, when it all came together.
