Vine staff
The vine staff, vine-staff, or centurion's staff (Latin: vitis) was a vinewood rod of about 1 m (3 ft) in length used in the ancient Roman army and navy. It was the mark and tool of the centurion: both as an implement in the direction of drill and maneuvers; and to beat wayward or laggard soldiers or sailors under his command. It was also borne by evocati who held an equivalent rank.
