[p. 113] When the Dutch came to America and established the colony of New Amsterdam, their children enjoyed the traditional "visit of Saint Nicholas" on December 5, for the Dutch had kept this ancient Catholic custom even after the Reformation. Later, when England took over the colony and it became New York, the kindly figure of Sinter Klaas (pronounced like Santa Claus) soon aroused among the English children the desire of having such a heavenly visitor come to their homes, too.
The English settlers were glad and willing to comply with the anxious wish of their children. However, the figure of a Catholic saint and bishop was not acceptable in their eyes, especially since many of them were Presbyterians, to whom a bishop was repugnant. In addition, they did not celebrate the feasts of saints according to the ancient Catholic calendar.
The dilemma was solved by transferring the visit of the mysterious man whom the Dutch called Santa Claus from December 5 to Christmas, and by introducing a radical change in the figure itself. It was not merely a "disguise," but the ancient saint was completely replaced by an entirely different character. Behind the name Santa Claus actually stands the figure of the pagan Germanic god Thor (after whom Thursday is named). Some details about Thor from ancient German mythology will show the origin of the modern Santa Claus tale:
Thor was the god of the peasants and the common people. He was represented as an elderly man, jovial and friendly, of heavy build, with a long white beard. His element was the fire, his colour red. The rumble and roar of thunder were said to be caused by the rolling of his chariot, for he alone among the gods never rode on horseback but drove in a chariot drawn by two white goats (called Cracker and Gnasher). He was fighting the giants of ice and snow, and thus became the Yule-god. He was said to live in the "Northland" where he had his palace among icebergs. By our pagan forefathers he was considered as the cheerful and friendly god, never harming the humans but rather helping and protecting them. The fireplace in every home was especially sacred to him, and he was said to come down through the chimney into his element, the fire. 70 [Note 70: H. A. Grueber, Myths of Northern Lands, Vol. I, New York, 1895, 61ff.]
[p. 114] Here, then, is the true origin of our "Santa Claus." It certainly was a stroke of genius that produced such a charming and attractive figure for our children from the withered pages of pagan mythology. With the Christian saint whose name he still bears, however, this Santa Claus has really nothing to do.
