This is one of several scenes of butchering that are present on the walls of a tomb chapel that originally stood in Saqqara and dates to the 5th Dynasty in the Old Kingdom (around 4500 years ago). The whole chapel is now in the Met Museum (acc. no.:08.201.1).
Butchering scenes were common in these chapels to provide meat for the deceased person in the afterlife. This one is on the west wall of the chapel, near the false door where offerings to the deceased were placed. So its likely function is to provide offerings in perpetuity.
Despite being a common scene type this example is still unusual. The museum website points out that it’s a stage in the process not normally represented – the cow is part butchered and its ribs are exposed now that the first cuts have been removed.
See it on my photo site: https://photos.talesfromthetwolands.org/picture.php?/1377/ And there are several other scenes from the walls to the right and left (11 in total).
