Traces of duality also exist in regional Day of the Dead celebrations. In urban centers it has been modified to appeal to tourist tastes, while its solemn, devotional nature is preserved in rural areas, where it remains a form of family reunion for the living and the dead. In villages all over Mexico, ofrendas, or offerings, of candles, fruit, flowers, food, and drink are prepared for the enjoyment of the returning souls of the dead. This movable feast is then taken to the cemeteries, where the living commune with the dead, bringing offerings of the delicacies they enjoyed in life. Families congregrate in cemeteries to clean the graves of loved ones, dressing them with incense burners fullof smoking copal and heaps of orange marigolds, or cemasuchules, the Aztec flower of the dead. Mariachis stand nearby, gently serenading the souls of the departed. It is a time when the living and the dead exist side by side, one reminding the other of the impermanency of life.
