A 4,000-year-old handprint has been discovered on a clay model used for offerings in an Ancient Egyptian tomb.

Researchers from Cambridge University’s Fitzwilliam Museum, in the United Kingdom, stumbled upon the imprint while preparing for an exhibition, which is set to open this fall.

It was found on the base of a “soul house,” a building-shaped clay model typically found in burials and said to have provided a place for the soul to live, according to a press release from the museum.

The model has an open space at the front where food offerings, like bread, lettuce or an ox’s head, could be placed.

Dating back to about 2055–1650 BCE, the soul house underwent extensive examinations that revealed how it was made four millennia ago.
