Nicholas learned of a poor man who had three daughters who could not afford to pay dowries for them to marry. He planned to sell his daughters into prostitution. Nicholas came late at night, on three different occasions, and dropped a bag of gold coins down the chimney so the man would have a dowry for each daughter.
Legend and tradition says that he did so that the three daughters of a poor man would have dowries and would not be sold into prostitution.
Nicholas of Myra would toss his gifts through an open window or down a chimney and would not personally enter a house.
Traditional folklore regarding Saint Nicholas of Myra says that he had a reputation for secret gift-giving, such as putting coins in the shoes of those who left them out for him. This turned into a folk-tale of him dropping coins down a chimney of a poor family and they fell into the stockings which had been hung to dry in the fireplace. That then turned into the chimney-descending we know today.

Saint Nicholas put gold coins in the stockings of the three daughters to serve as dowries so that they could get married. This act of generosity became the basis for the tradition of hanging stockings by the fireplace that is practiced during Christmas time.
