In Spain, Argentina, and Uruguay, children (and many adults) polish and leave their shoes ready for the Kings' presents before they go to bed on 5 January. Sweet wine, nibbles, fruit and milk is left for the Kings and their camels. In Mexico, it is traditional for children to leave their shoes out on the evening of January 6, sometimes filling them with hay for the camels, so that the Kings will be generous with their gifts. In Puerto Rico, it is also a tradition for children to fill a box with grass or hay and put it underneath their bed, for the same reasons.
Also, the Epiphany (aka "The Adoration Of The Magi") is a triptych painted by Hieronymus Bosch.
