This is a captured image before the recent horrific restoration of the Lamb. https://www.cnn.com/style/article/ghent-altarpiece-restoration-scli-intl/index.html
This is the center panel of the Ghent Altarpiece showing an altar on which the Lamb of God is positioned, standing in a verdant meadow, while the foreground shows a fountain. Five distinct groups of figures surround altar and fountain. In the mid-ground two further groups figures are seen gathering; the dove of the Holy Spirit is above. The meadow is framed by trees and bushes; with the spires of Jerusalem visible in the background. Dhanens says the panel shows "a magnificent display of unequaled color, a rich panorama of late medieval art and the contemporary world-view." The iconography, suggested by the groupings of the figures, appears to follow the liturgy of All Saints Day.
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; ECCE AGNUS DEI QUI TOLLIT PECCATA MUNDI ("Behold the Lamb of God who takes away the sins of the world"). The lappets bear the phrases IHESUS VIA ("Jesus the Way") and VERITAS VITA ("the Truth, the Life").
The illumination contrasts with the natural and directional lighting of the four upper interior wings, and of each of the outer wings. It has been interpreted as a device to emphasize the presence of the divine and accentuate the paradise of the central landscape. The dove as the Holy Spirit, and the lamb as Jesus, are positioned on the same axis as that of God The Father in the panel directly above; a reference to the Holy Trinity.
