Lam Gods

Last week a face has been found in the underdrawing on Van Eyck's Ghent Altarpiece or 'Adoration of the Mystic Lamb' (1432). This video is in Dutch, but is quite self-explanatory. 
Infrared reflectography of the Altarpiece as a whole or in its very smallest details can be seen in high resolution images on this website. Or scroll through its magnificent history of whereabouts through this serie of photos and news articles.
