The lamb stands on an altar, and is surrounded by 14 angels arranged in a circle, some holding symbols of Christ's Passion, and two swing censers. The lamb has a wound on its breast from which blood gushes into a golden chalice, yet it shows no outward expression of pain, a reference to Christ's sacrifice. The lamb has a human-like face which appears to be looking directly out of the panel, similar to the subjects of Jan van Eyck's single head portraits. The angels have multicolored wings and hold instruments of Christ's passion, including the cross and the crown of thorns. The antependium on the upper portion of the front of the altar is inscribed with the words taken from John 1:29; ("Behold the Lamb of God who takes away the sins of the world"). The lappets bear the phrases ("Jesus the Way") and ("the Truth, the Life").
