Robert de Shurland's Horse Skull

Origin
This ironic artifact originally belonged to the horse of sir Robert de Shurland.

According to legend, Sir Robert killed a monk and resolved to ask the king for a pardon. In 1327 he rode to where the king's ship was anchored, off the Isle of Sheppey, and gained forgiveness. Returning, he met a witch who said that de Shurland's horse, Grey Dolphin, which had borne him so bravely to the ship, would be the death of him. Sir Robert immediately killed the horse and cut off its head. A year later Sir Robert was walking along the shore when a shard of the horse's bone pierced his foot. Blood poisoning set in and Sir Robert died.
