Cremation is the practice of reducing a human body into its most essential element with the use of fire. it is suspected that the practice of cremation in the ancient times started during the Stone Age somewhere near Europe.
It was only during the late Stone Age that the practice of cremation started to be adopted throughout northern Europe with the use of decorative urn for preserving the cremated remains of the dead.
Crematoriums were being established sometime in the Bronze age in Hungary and Northern Italy spreading to Northern Europe and Ireland.
In the Mycenaean Age cremating the dead became an integral part of the Grecian burial custom. But by 400 AD, after the christianization of Constantine, earth burial completely replaced the practice of cremation since it was considered as a pagan custom by the Christians.
