This is going to be a banner year for Winter Solstice parties. If superstitious, you can choose to use the following theme on December 21. Or, opt to do a quiet solo meditation on that date. Then when you're still around to enjoy 2013, have a "The Mayans Were Misinformed" hootenanny to ring in the new year.
According to Lee Cart in the Suite 101 website article, "The Sacred Colors of the Ancient Maya," (January 20, 2011), the Mayan colors were red for the east and the birth of the sun, yellow for the south, black for death and the west, and white for north. You can construct an altar with a blue green candle for a centerpiece, as this was the fifth color and direction, believed to connect the other four cardinal elements. Incidentally, east/red was seen as the most important and should be placed at the typical north spot of your construction. Sacred plants and foods to the Mayans were wild corn, bees, flowers and beans. Choose one of each of these items to place at its corresponding color and direction– I would opt for yellow honey instead of actual bees, though.
Clare Green's, "The Ancient Maya Diet," (July 23, 2009) at the Discover Chichenitza website contains helpful menu ideas. Some of the staple foods of the Mayan diet that Green lists are: corn, pumpkins, sweet potatoes, tomatoes, chili peppers, pineapple, shrimp, avocado, and chocolate. You can use heat and serve products from your local organic food store or try out out some of the fun recipes here: http://car.utsa.edu/Legacy/mayarecipes.htm
