Santa's origin can be traced back to ancient Germanic folklore and the Norse god Odin. The modern character of Santa was embraced by America with the December 23, 1823 publication of Clement Clarke Moore's 56 line poem "A Visit from St. Nicholas," better known as "Twas the Night Before Christmas." Here is Moore's description of the jolly fatman:
Down the chimney St. Nicholas came with a bound.
He was dressed all in fur, from his head to his foot,
And his clothes were all tarnished with ashes and soot;
A bundle of Toys he had flung on his back,
And he looked like a pedler just opening his pack.
His eyes—how they twinkled! his dimples how merry!
His cheeks were like roses, his nose like a cherry!
His droll little mouth was drawn up like a bow
And the beard of his chin was as white as the snow;
The stump of a pipe he held tight in his teeth,
And the smoke it encircled his head like a wreath;
He had a broad face and a little round belly,
That shook when he laughed, like a bowlful of jelly.
He was chubby and plump, a right jolly old elf,
And I laughed when I saw him, in spite of myself
