A peltast (‹See Tfd›Greek: πελταστής, peltastes) was a type of light infantry originating in Thrace and Paeonia and named after the kind of shield he carried.[1] Thucydides mentions the Thracian peltasts, while Xenophon in the Anabasis distinguishes the Thracian and Greek peltast troops.[2]
The peltast often served as a skirmisher in Hellenistic armies. In the Middle Ages, the same term was used for a type of Byzantine infantryman.
