Calibrated optical imagery performed to study the morphology of the radio galaxy 3C 120 is reported. Both H-alpha and forbidden O III 5007 A emission-line images contrast strongly with previous reports. The barred shape of the galaxy is outlined by the distribution of the giant H II regions detected around the bright core. The conspicuous surrounding emissions display a 'Z' structure within a 1 arcmin field of view covering 40 kpc if H0 = 75 km/s/Mpc. The elongated core would have two components roughly aligned with P.A. = -25 deg. The earlier 'edge-on'structure is resolved in three components: the main double elliptical core extended by two N-S condensations of about 5 arcsec in extent. The radial 4 arcsec westward extension detected in two emission lines coincides with the 6 cm and 20 cm radio jets, supporting the line-emitting gas tendency to spread in the same direction as the radio ejecta. Absolute fluxes are given for several positions of interest as well as for the whole galaxy.
