A significantly more technical and advanced study of Mycenaean burials and grave goods. After reading one of the general religion resources and the above source, this will be excellent to provide further details.
The Mycenaeans believed in a physical afterlife, which is evident through their treatment of the dead. In the early phases of the Late Helladic single inhumations in pits or cist graves was widespread. These burials often contained a small amounts of jewelry and pottery. Elite grave groups were occasionally covered in a tumulus while other elite and royal burials were in shaft graves (Mycenae: Grave circle A and B). Later these early burial types still appear; however, chamber tombs become more popular. For elites and royalty tholos tombs, often monumental, are popular.
