January 6th is the Feast of the Epiphany which commemorates the arrival of the Magi in Bethlehem.
To atone for her tardiness, on every Epiphany Eve la Befana travels on her magic broom to every home in Italy bringing candy to the nice children and coal, onions or garlic to the not so nice.
La Befana vien di notte
con le scarpe tutte rotte
col cappello alla romana
viva viva la Befana!
