Probably early 1800s
This curious object is made from the bone vertebra of a cow, oxen, or horse. It depicts a preaching clergymen, possibly but not necessarily Methodist, and is a piece of folk art.
Although unusual, this piece is not unique. There are three similar vertebra preacher statuettes in the Collection at Wesley's Chapel, and occasionally one comes across them in museums and private collections. The material, colouring and the bone 'wings' at the back make these small statues appear rather sombre.
This particular statuette has very distinctive facial features and may be a portrait painted from life.
