πηδάλιον (πηδόν): steering-oar or rudder, Od. 3.281, Od.
5.255. (Strictly, the word probably denotes the handle or bar connecting the two rudders, and serving to move them.
See cuts Nos. 87, 88, and cf. Nos. 37, 38, 60. The adjoining cuts
represent the rudders of Egyptian ships; in the first cut both rudders
are depicted as on one side of the vessel.)
