I enjoy your historical posts for the very reason that they demonstrate a common human condition when it comes to burial. Stones to make the site visible and also inaccessible to wild animals. Somewhere close to the city but not in the center so the dead can have "peace" as well as for health reasons.

Every human culture understood this basic concept whether they build pyramids or hill tops for grave. They all elevated the ground in a different way, as a reminder where we will all end up one day.
