The Christmas season in Mexico starts on December 16 with "las posadas," a series of religious processions in which families or neighbors reenact Joseph's search for shelter for Mary en route to Bethlehem. Those representing pilgrims travel from home to home until they are finally accepted by those representing innkeepers at a home with a "nacimiento" (nativity scene). There the pilgrims place figures representing Mary and Joseph. On Christmas Eve, the Christ Child is laid in the manger. Then children break a "pinata," a decorated, candy-filled earthen or papier mache container, to complete "las posadas." The Mexican Christmas tradition incorporates legends surrounding poinsettias, roosters, and decorative displays using much light, including fireworks and "farolitos" (candles inside paperbags). Customs include exchanging gifts, eating grapes for good luck, and singing Spanish Christmas songs. January 6 is the "Dia de los Reyes," (Day of the Kings) celebrating the arrival of the three "Wise Men." Gifts are again exchanged, and a "rosca" (special cake) is baked with a tiny porcelain doll inside. Whoever is served the piece with the doll must give a party on February 2, the date the Christ Child is removed from the "nacimiento." The words to a traditional Mexican carol are attached. (MM)
