I recently listened to a series of popular lectures on Mesoamerican history. According to it, most classical Mesoamerican cultures worshiped their ancestors in one way or another. Many considered their deceased ancestors a link to the other world. Maya even buried their ancestors under their houses.

Many of the native beliefs and traditions have perpetuated well into the colonial era. Do we have any evidence that some of them may have influenced the Day of the Dead tradition in Mexico?
