Thirteen figures sit along one side of a long table covered in a white cloth with blue-striped ends. Christ is in the middle, in a red robe and blue mantle, with his hands resting calmly on the table. The apostles lean, gesture and turn toward one another in clusters on both sides of him.

The room recedes in strict perspective to three windows behind Christ. The middle window opens onto a pale blue landscape. The coffered ceiling and dark wall hangings frame the scene in muted browns and earth tones. Small plates and bread rolls dot the tabletop. The red, blue and green robes stand out against the warm, shadowed architecture.
