About this work
Subject & Meaning
On the inner surface, the painting illustrates the Circumcision of Christ, a biblical event marking the naming of Jesus eight days after his birth.
The artwork depicts two distinct religious scenes on opposite sides of a single altarpiece wing. On the inner surface, the painting illustrates the Circumcision of Christ, a biblical event marking the naming of Jesus eight days after his birth. The outer face features the Virgin Mary, representing the moment of the Annunciation when she is visited by the angel Gabriel.
As a religious genre piece created in 1520, the work functions as a devotional object within an altarpiece structure. The dual imagery connects the Incarnation on the exterior with the fulfillment of Jewish law on the interior, serving the liturgical and spiritual needs of its original setting.
