I came across this architectural fragment on our recent visit to Corinth, Greece. It depicts an sailor steering a ship using a oar. These oversized oars, steering oars, or quarter rudders were a common apparatus on vessels throughout the Greco-Roman period. On larger ships they were lashed or attached to the ship to ease the labor of the pilot.
The true sternpost rudder seems to have originated in first-century China. Only later did Mediterranean shipwrights adapt the technology.
The stern of the ship depicted here is adorned with a goose-head, a common motif of Roman merchantmen.
