Centurio

A centurion (/sɛnˈtjʊəriən/; Latin: centurio [kɛn̪ˈt̪ʊrioː], pl. centuriones; Greek: κεντυρίων, translit. kentyríōn, or Greek: ἑκατόνταρχος, translit. hekatóntarkhos) was a position in the Roman army during classical antiquity, nominally the commander of a century (Latin: centuria), a military unit of around 80 legionaries. In a Roman legion, centuries were grouped into cohorts commanded by their senior-most centurion. The prestigious first cohort was led by the primus pilus, the most senior centurion in the legion and its third-in-command.

A centurion's symbol of office was the vine staff, with which they disciplined even Roman citizens, who were otherwise legally protected from corporal punishment by the Porcian Laws.[citation needed] Centurions also served in the Roman navy. After the 107 BC Marian reforms of Gaius Marius, centurions were professional officers. In Late Antiquity and the Middle Ages, the Byzantine army's centurions were also known by the name kentarch (Greek: κένταρχος, translit. kentarchos).[1]
