The optical properties of the z = 0.435 quasar PKS 1222+216 (4C+21.35) aresummarized since the discovery of impressive gamma-ray activity in this sourceby Fermi/LAT. Unlike several other gamma-ray-bright blazars, there appears tobe little connection between optical and gamma-ray activity. Spectropolarimetryshows this object to be a composite system with optical emission from both apolarized, variable synchrotron power-law and unpolarized light from a stableblue continuum source (+broad emission-line region) contributing to theobserved spectrum. Spectrophotometry over a period of about two years does notdetect significant variability in the strong, broad emission lines, despitelarge optical continuum variations. This suggests that the relativistic jet haslittle influence on the output of the broad emission-line region, possiblyeither because the highly beamed continuum ionizes only a small portion of theline-emitting gas, or the observed non-thermal continuum originates parsecsdownstream from the base of the jet, further away from the central engine thanthe broad emission-line region.
