Lancer of the 3rd century AD, armed in Sarmatian manner, from the marble stele of Tryphon found in the ruins of the Bosporan centre of Tanais on the Don, which was then dominated by the Alans (Ammianus 'Tanaitae'). The clean-shaven, long-haired rider wears a rounded cap or helmet, without cheekpieces or neckguard. His scale corselet is secured by a broad belt, and worn over a long-sleeved undergarment and trousers. The rider's legs seem to curve under the belly of his relatively small horse. He holds his long lance with both hands. (After Rostovtev)

Rather like a grave relief is Tryphon's dedication from Tanais (Fig. 2 18). The type recalls the coins of Cotys II (P1. VIII. 4), terra-cottas from Kerch⁷, and a clasp in the form of a horseman from Sympheropol⁸. From this latter site come reliefs of Tauri (?), one a trousered rider, early IVth century, the other with two fields, in one a horseman, in the other a spearman in a doublet with a small targe⁹.
