distinctions must be made between intentionally prepared aztec mummies and mummies resulting from natural desiccation. prepared aztec mummy “bundles” consist of the remains of the deceased placed in a woven bag or wrap which was often adorned with a ceremonial mask. most of the more widely known examples of aztec mummies, which formed the basis of popular traveling exhibitions and museum exhibits in the 19th century, were likely the product of natural desiccation rather than an intentional mummification process.
