Darmstadt Altarpiece: Constantine and His Mother Helena Venerating the True Cross

The Darmstadt Altarpiece panel showing Constantine and Helena venerating the True Cross connects the central Passion narrative of the altarpiece to the history of the relic's discovery in Jerusalem. Helena, mother of Constantine, was credited in medieval legend with finding the True Cross through excavation on Golgotha in 326 AD, and both figures were venerated as saints in the Eastern and Western churches. Including them in a Passion altarpiece program tied the devotional object's veneration of the cross directly to historical events that authenticated the relic, functioning almost as a provenance claim for the sacred wood being depicted throughout the cycle.

Constantine's imperial costume and Helena's queenly dress provide the artist with an opportunity for more elaborate and decorated painting than the Passion scenes allow, with gold brocade, crowns, and heraldic detailing rendered in the refined manner of International Gothic courtly painting.
