Jeff Ziegler gives us these feast-day links on St. Nicholas:

— Today is … the optional memorial of St. Nicholas, (d. fourth cent.), bishop, patron of children, bankers, pawnbrokers, sailors, perfumers, brides, unmarried women, travelers, fishermen, dockworkers, brewers, poets, prisoners, Russia, Greece, Sicily, Lorraine, and Apulia.
— Pope Benedict in Bari (2005), where the saint’s relics are venerated.
— Beato Angelico, “Stories of St Nicholas of Bari.”

And I posted this post last month, on The Original North Pole.
