Ancient Greek name (Νικόλαος) [Nikolaos], comes from the ancient Greek words νίκη [niki] - "victory" + λᾱός [laos] - "army, infantry; people"="victorious army; victory of the army; victory of the people; people`s conqueror; of the winner people".
Saint Nicholas (Santa Claus)(270 - 6 December 346) is the canonical and most popular name for Nikolaos of Myra, a Saint and Greek Bishop of Myra. Because of the many miracles attributed to his intercession, he is also known as Nikolaos the Wonderworker. 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 English name comes from the Dutch Sinterklaas. His reputation evolved among the faithful, as is 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.
