I haven't looked into this in depth, so I'll just quote E. J. Kenney again:
„Apuleius' readers would have been familiar with a wide range of works of art of every conceivable kind in which two symbolic figures identified as Eros and the Soul are represented in a variety of situations, sometimes in harmony, sometimes in discord: now embracing (sometimes with nuptial concomitants), now one tormenting or being tormented by the other. These themes occur also in epigrams, particularly those of Meleager. From the enormous extent and variety of the iconographic material it is apparent that there was no single myth of Eros and Psyche, rather a potentially unlimited range of applications of two highly versatile symbols, attractive to artists not only as profoundly suggestive but also as lending themselves to exploitation in innumerable forms, from the merely pretty or whimsical to the tragic or near sadistic. The monuments do not yield a single coherent picture or narrative which can be posited as a source for his story.” (Apuleius: Cupid and Psyche)
