The warm colours ranging from dark red and russet to yellow, green, grey and black are distinctive. Another typical feature is the expressionless faces of the sleepy-eyed people, turned to the left or right while their bodies face the front. All the images, including the surrounding stonework, are decorated with ornaments such as stars, plants and trees. The images themselves appear to have been inspired partly from block-prints from a Dutch or German Biblia Pauperum, a book containing some 40 pages of drawings depicting stories from the Bible.
