This sculpture would have most probably once decorated a lintel or, more likely, the roof-line of a church. It would have been a part of a series of corbels that would have worked together to embellish but also to support the roof. The careful treatment of this head and it's chimerical character were meant to strike the Christian spirits of the time. This work is emblematic of both the decorative and apotropaic value (protection against the evil forces) which exterior sculpture of Medieval buildings oftently assumed. The monster, very stylized, with large eyes and pointed horns, seems to rise from the stone, more grotesque than frightening. The head of this fantastic chimera seems to privilege a graphic treatment of the stone above all scholarly meaning of the relief.
From the twelfth century, the idea that the spirit of evil can materialize in a half-human, half-animal aspect, probably contributed to the multiplication of strange images representing the demonic forces working to the loss of Man's Life. It is significant that such representations are most often placed outside sacred buildings, as if to symbolize sins and vices that have no place in the sanctuary space, a meeting place between God and the faithful.
