Mid-sixteenth-century
A nude man and woman are shown stood with a tree between them. A creature with a serpent body and human face is shown around the tree.
The boss represents the recognisable Biblical narrative of Adam and Eve in which a serpent tempts the two to commit the first sin. Multiple parts of the story are shown at the same time in this single carving allowing the whole story to be told at once. For instance, the snake and Adam are both shown holding apples and the two figures cover their nudity which occurs at the end of the narrative. This compression of the scene is common in medieval iconography.
The serpent is also shown with a human face as typically in this period the snake is shown as a reflection of Eve. This may indicate the original sin as being hers.
The nave ceiling was repainted in 1865.
