Swiety Mikolaj is
St. Nicholas-based Yuletide and makes his rounds on December 6. Resembling
a bishop, he wears a mitre (religious hat) and a long cape-style garment,
carrying a staff. Rather than letters to Santa at the North Pole, Polish
children leave their notes on the window sill, hoping to receive a present
in return.
If they do not, there is always Gwiazdka, Star of Giving, a feminine
personification of the Christmas Star. Following the Christmas Eve supper,
there is a visit from the Star Man, usually the village priest, who tests
the children in their Catechism and rewards them with gifts.
