In this paper, I address one characteristic of Classical Greek votive reliefs that has troubled scholars: the size of the gods. The reliefs depict mortal worshippers approaching gods and goddesses who are, almost invariably, larger in stature than the mortals. Scholars have generally explained the difference in scale to be art historical, rather than theological, in significance. Either the larger scale is a visual expression of the hierarchical superiority of the gods or the images of the gods represent over-life-size statues. In addition, it is widely accepted that votive reliefs are products of unsophisticated religious belief, ignorant of the conceptualization of an imperceptible, non-corporeal deity in Classical philosophy. In this paper, I accept the artistic proposition of votive reliefs at face value: in this genre, the gods are living, visible, material bodies, most often anthropomorphic in form and always larger in magnitude than mortals. I identify one significant parallel for this interpretation within Greek and Roman thought, namely, the conception of gods within the materialist theology developed by the late Classical writer Epicurus and, in part at least, by the fifth-century BC writer Demokritos. In the writings of the Epicureans and, it appears, the atomists, as in the votive reliefs, gods are human in form, very beautiful, self-sufficient, larger than humans in size and known by mortals through visual perception.
