Today is the last day of the Day of the Dead (Día de los Muertos). Honoring the dead occurs in ancient cultures all over the world, and even in modern times it plays an important role in religions. It is founded on the belief that the dead live on and are able to influence the lives of later generations. These ancestors can assert their powers by blessing or cursing, and their worship is inspired by both respect and fear. Rituals consist of praying, presenting gifts, and making offerings. In some cultures, people try to get their ancestors' advice through oracles before making important decisions.
The dead are believed by the peasantry of many Catholic countries to return to their former homes on All Souls’ Night and partake of the food of the living. In Tyrol, cakes are left for them on the table and the room kept warm for their comfort. In Brittany, people flock to the cemeteries at nightfall to kneel, bareheaded, at the graves of their loved ones, and to anoint the hollow of the tombstone with holy water or to pour libations of milk on it. At bedtime, the supper is left on the table for the souls. In Bolivia, many people believe that the dead eat the food that is left out for them. Some claim that the food is gone or partially consumed in the morning.
