In late antiquity, both the nature of images and the treatment accorded to them generated deeply divisive debates. Portraits of human subjects were an accepted convention, but offering reverence to them might be controversial. Art historian Thomas F. Mathews here retells the story from the Acts of John about the apostle’s rejection of the pagan-style honours—garlands, lamps, and an altar—given to the portrait secretly made of him, in gratitude for being raised from the dead, by the praetor of Ephesus Lykomedes. The third-century Platonist Plotinus, likewise the subject of a surreptitious portrait, went even further and questioned the very purpose and meaning of creating an image of an image: “Isn’t it enough that I have to carry around the image that nature has clothed me with?” (Porphyry, Life of Plotinus 1). As for images of divine beings, Clement of Alexandria condemned the masterpieces of the sculptor Lysippus and the painter Apelles, leading Greek artists of the fourth century BC, as examples of a “deceitful art” that vainly seeks to emulate God’s perfection (Exhortation to the Heathens 4). Nevertheless, the gods continued to be depicted both in statues and on movable wooden panels. Clement specifically mentions lewd paintings of Aphrodite “hung on high like votive offerings” in pagans’ bedrooms. Comparison is unavoidable with the emergent Christian genre of the icon. It is to documenting and speculating on these resemblances and possible continuities that Mathews addresses himself in this elaborate and sumptuously illustrated publication from the J. Paul Getty Museum.
