Grave goods can be regarded as a sacrifice intended for the benefit of the deceased in the afterlife. Closely related are customs of ancestor worship and offerings to the dead, in modern western culture related to All Souls' Day (Day of the Dead), in East Asia the "hell bank note" and related customs. Also closely related is the custom of retainer sacrifice, where servants or wives of a deceased chieftain are interred with the body. As the inclusion of expensive grave goods and of slaves or retainers became a sign of high status in the Bronze Age, the prohibitive cost led to the development of "fake" grave goods, where artwork meant to "depict" grave goods or retainers is produced for the burial and deposited in the grave in place of the actual sacrifice.
