Saint Nicholas (Ἅγιος Νικόλαος, Hagios ["Saint", literally "Holy", Latin: Sanctus] Nicolaos ["victory of the people"]) (270 - 6 December 343) also called Nikolaos of Myra, was a historic 4th-century saint and Greek Bishop of Myra (Demre, part of modern-day Turkey) in Lycia. Because of the many miracles attributed to his intercession, he is also known as Nikolaos the Wonderworker (Νικόλαος ὁ Θαυματουργός, Nikolaos ho Thaumaturgos). He had a reputation for secret gift-giving, such as putting coins in the shoes of those who left them out for him, and thus became the model for Santa Claus, whose modern name comes from the Dutch Sinterklaas, itself from a series of elisions and corruptions of the transliteration of "Saint Nikolaos". His reputation evolved among the faithful, as was common for early Christian saints. In 1087, his relics were furtively translated to Bari, in southeastern Italy; for this reason, he is also known as Nikolaos of Bari. His feastday is 6 December [O.S. 19 December].The tradition of Saint Nicholas Day, usually on 6 December ( O.S.19 December in most Orthodox countries), is a festival for children in many countries in Europe related to surviving legends of the saint, and particularly his reputation as a bringer of gifts. The American Santa Claus, as well as the Anglo-Canadian and British Father Christmas, derive from these legends. "Santa Claus" is itself derived from the Dutch Sinterklaas
In Northern Germany, Nikolaus is usually celebrated on a small scale. Many children put a boot called Nikolaus-Stiefel (Nikolaus boot) outside the front door on the night of 5 December. St. Nicholas fills the boot with gifts and sweets overnight, and at the same time checks up on the children to see if they were good, polite and helpful the last year. If they were not, they will have a tree branch (Rute) in their boots instead.
Sometimes a Nikolaus impersonator also visits the children at school or in their homes and asks them if they have been good (sometimes ostensibly checking his golden book for their record), handing out presents on the basis of their behavior. This has become more lenient in recent decades, and this task is often taken over by the Weihnachtsmann (Santa Claus). In more catholic regions, Nikolaus is dressed very much like a bishop and rides on a horse, welcomed at public places by a large crowd.
Typical in the German speaking countries for Saint Nicholas Day is the Stutenkerl, a pastry made of sweet leavened dough.
