There has been a good deal of discussion in recent literature about the hypothesis, first put forward by Barnothy and Barnothy (1968), that quasars could be gravitationally lensed nuclei of Seyfert's galaxies (Turner, 1980; Tyson, 1981). Large amplifications (> 3–4 magnitudes) are needed to account for the widespread distribution in the intrinsic optical luminosities of quasars. A direct verification of this hypothesis is difficult to achieve due to the limited angular resolution of ground based telescopes. However, this hypothesis may be tested in a global sense by referring to radiation properties of Sy 1 nuclei which must be preserved, or must change in any predictable way, through the lensing process.
