Rapunzel

A witch, having demanded a couple's unborn child as payment for stolen vegetables, took the baby girl at birth and named her Rapunzel, raising her in isolation and eventually locking her, at twelve years old, in a tower with no door or stairs, only a high window. Whenever the witch visited, she would call up "Rapunzel, Rapunzel, let down your hair," and climb up the girl's impossibly long golden braid.

A prince, passing through the forest, overheard the witch's call and, once she left, tried the same words himself, climbing up to meet Rapunzel. The two fell in love and planned her escape, but the witch discovered their secret meetings, furiously cut off Rapunzel's hair, and banished her to a desolate wilderness. When the prince next called up, the witch lowered the severed braid herself and, once he climbed to the top, pushed him from the tower in fury. He survived the fall but was blinded by thorns below.

For years the blinded prince wandered, until he stumbled upon Rapunzel, now living simply with the twins she had borne him. Her tears of joy at finding him fell into his eyes and restored his sight completely, and the two returned together to his kingdom, where they lived happily for the rest of their lives.
