Cuckold's Horn

The drinking horn of King Arthur, brought to him by a mysterious boy. It gave warning of infidelity, and no one who was either unfaithful in love or disloyal to his liege lord could drink from it without spilling the liquor.

The French Coupe Enchantée possessed a similar property.

The same boy brought also a mantle with similar characteristics. If one who was unfaithful in love, false in domestic life, or treacherous to the king, attempted to wear the robe, it would pucker up, hung slouching, or tumble to pieces.
