Agnus Dei (1639)

This 1639 Agnus Dei is one of several versions Zurbarán painted of a bound lamb on a stone slab, a subject uniquely associated with his art. The image functions simultaneously as a naturalistic animal study and a profound theological symbol of Christ's sacrificial death. Zurbarán's austere, powerfully meditative style—white-robed monks in intense chiaroscuro, saints presented against dark backgrounds with sculptural solidity—made him the ideal painter for the Counter-Reformation religious orders of Extremadura and Seville.

The lamb lies with its legs bound on a stone surface, rendered with photographic accuracy—each curl of wool individually described. The absolute simplicity of the dark background transforms the naturalistic study into a devotional icon of remarkable power.
