Aries or the Agnus Dei: is the zodiac pagan or Christian in medieval art?

Abstract

The title for this article is inspired by the questions repeatedly asked by my students, and this study attempts to break the question apart and reconsider the language used to study the zodiac in medieval art. The terms ‘pagan’, ‘Christian’ and ‘Christianising’ are problematic and create misleading binaries, so first I reframed the question by carefully redefining the terms used to describe the zodiac in medieval art. I further refined the query to one central question: Why did the signs of the zodiac, and the constellations generally, persist in their Hellenistic renderings in art and texts into the Christian era and beyond, and not reinvented with more religiously-appropriate signifiers? Drawing from contemporary texts and art, I suggest that there were two cultural forces perpetuating the Hellenistic zodiac: the methods of dissemination of astronomical knowledge from classical sources, and the active creation of zodiacal art. I explore how the folkloric authority of the zodiac signs synergistically combined with the visual arts to stimulate astrological practices. I argue that art production was crucial as an advancing influence and not simply a by-product of a classical inheritance.
