The importance of wells in men's lives is also linked to the belief that by expressing a desire in the vicinity of these structures or throwing a coin into the water their wish would be granted or may favor the favour of the deities residing in the under world. Of this tradition, extended in all the cultures of the world, some popular expressions are born:  "The Well of desires "  "Find the moon in the Well ", present in the legacy of many countries fairy tales, or  "St. Patrick's Well ", known as a Place where large quantities of things accumulate, originally valuable. The authentic St. Patrick's Well, in Ireland, is a cavity shown by God to the saint to be able to pray and point out to men the Sorrows of hell: Whoever pushed himself to the bottom of the "well" would have obtained eternal salvation.
