Amniomancy is a method of divination whereby the future life of a child is predicted from the caul covering their head at birth.
[1][2] The colour and consistency of the caul are used to interpret the future.
[3] Amniomancy dates to at least the times of the Roman Empire.
[4] The word amniomancy comes from the Latin amnion, meaning membrane.
[5] The French proverb Il est ne coiffe is thought to originate from this practice.
