In Vikings, a pre-Christian Scandinavian society is shown as burning the dead in a funeral. This is similar to how the Hindus and quite a few other cultures did it.
They even hint at how burying the dead was a sign of insulting them.
Most modern Abrahamic cultures—Christian, Muslim and Jewish—bury their dead. I’m guessing the modern, Christian Scandinavians bury their dead too. Made me wonder.
The Abrahamic religions started in the middle east in arid, often desert, land. Wood from trees must have been at a premium, so funeral by burning would’ve been expensive. Maybe that’s why they chose burial over burning.
Later, these religions spread to other areas with no paucity of wood, but the religious norm—burying not burning—went along. Even areas where there was plenty of wood, but relatively little accessible land ended up burying the dead instead of burning them.
Coming back to the Vikings, burning made sense for them. Wood was, and is, relatively plentiful in Scandinavia. Moreover, the ground would be frozen hard through long winters, making digging for a burial hard. But once Christianity came in, the new socioreligious norms quickly overturned old wisdom.
It may be the same in parts of southeast Asia where the pre-existing religions—Hinduism, Buddhism and native religions—would’ve burned their dead. Yet, after the adoption of Islam, most societies turned to burial. Despite plenty of thick tropical forests for wood, and expense of clearing land (or lack of it on islands) for burial.
