A retiarius (plural retiarii; literally, "net-man"or "net-fighter"in Latin) was a Roman gladiator who fought with equipment styled on that of a fisherman: a weighted net (rete, hence the name), a three-pointed trident (fuscina or tridens), and a dagger (pugio). The retiarius was lightly armoured, wearing an arm guard (manica) and a shoulder guard (galerus).
