December 22 2014 Everyone knows who Santa is, but do you know things about him? The man we know as Santa Claus has a history all his own. Today, he is thought of mainly as the jolly man in red, but his story stretches all the way back to the 3rd century and it is the 21 first century now!One of the best known of the St. Nicholas stories is that he saved three poor sisters from being sold into slavery or prostitution by their father by providing them with a ring to be married.His feast day is celebrated on the anniversary of his death, December 6. This was traditionally considered a lucky day to make large purchases or to get married. By the Renaissance, St. Nicholas was the most popular saint in Europe.The name Santa Claus evolved from Nick’s Dutch nickname, Sinter Klaas, a shortened form of Sint Nikolaas (Dutch for Saint Nicholas). In 1804, John Pintard, a member of the New York Historical Society, distributed woodcuts of St. Nicholas at the society’s annual meeting. The background of the engraving contains now-familiar Santa images including stockings filled with toys and fruit hung over a fireplace.Santa is called by a variety of names: Saint Nickolas, Santa Clauses, Father Christmas, Sinter Klaas, and the list goes on. Merry Christmas.
