A sarcophagus is a stone coffin that often holds the remains of a deceased person. These structures are typically elaborately decorated and can be found in various cultures, most famously in ancient Egypt. They were designed to protect the body and provide a resting place for the soul in the afterlife. Sarcophagi can be made from different materials, including marble, limestone, or granite. They often feature intricate carvings or inscriptions that reflect the beliefs and status of the individual buried within, making them significant artifacts for understanding ancient civilizations and their burial practices.
