Cremation is a method of final disposition of a dead body through burning.
Cremation may serve as a funeral or post-funeral rite and as an alternative to burial. In some countries, including India and Nepal, cremation on an open-air pyre is an ancient tradition. Starting in the 19th century, cremation was introduced or reintroduced into other parts of the world. In modern times, cremation is commonly carried out with a closed furnace (cremator), at a crematorium.
Cremation leaves behind an average of 2.4 kg (5.3 lbs) of remains known as "ashes" or "cremains". This is not all ash but includes unburnt fragments of bone mineral, which are commonly ground into powder. They do not constitute a health risk and may be buried, interred in a memorial site, retained by relatives or scattered in various ways.
History
Ancient
Cremation dates from at least 17,000 years ago in the archaeological record, with the Mungo Lady, the remains of a partly cremated body found at Lake Mungo, Australia.
Alternative death rituals which emphasize one method of disposal – burial, cremation, or exposure – have gone through periods of preference throughout history.
In the Middle East and Europe, both burial and cremation are evident in the archaeological record in the Neolithic era. Cultural groups had their own preferences and prohibitions. The ancient Egyptians developed an intricate transmigration-of-soul theology, which prohibited cremation. This was also widely adopted by Semitic peoples. The Babylonians, according to Herodotus, embalmed their dead. Phoenicians practiced both cremation and burial. From the Cycladic civilization in 3000 BCE until the Sub-Mycenaean era in 1200–1100 BCE, Greeks practiced burial. Cremation appeared around the 12th century BCE, probably influenced by Anatolia. Until the Christian era, when inhumation again became the only burial practice, both combustion and inhumation had been practiced, depending on the era and location. In Rome's earliest history, both inhumation and cremation were in common use among all classes. Around the mid-Republic inhumation was almost exclusively replaced by cremation, with some notable exceptions, and remained the most common funerary practice until the middle of the Empire, when it was almost entirely replaced by inhumation.
In Europe, there are traces of cremation dating to the Early Bronze Age (c. 2000 BCE) in the Pannonian Plain and along the middle Danube. The custom became dominant throughout Bronze Age Europe with the Urnfield culture (from c. 1300 BCE). In the Iron Age, inhumation again becomes more common, but cremation persisted in the Villanovan culture and elsewhere. Homer's account of Patroclus' burial describes cremation with subsequent burial in a tumulus, similar to Urnfield burials, and qualifying as the earliest description of cremation rites. This may be an anachronism, as during Mycenaean times burial was generally preferred, and Homer may have been reflecting the more common use of cremation at the time the Iliad was written, centuries later.
Criticism of burial rites is a common aspersion by competing religions and cultures, including the association of cremation with fire sacrifice or human sacrifice.
Hinduism and Jainism are notable for not only allowing but prescribing cremation. Cremation in India is first attested in the Cemetery H culture (from c. 1900 BCE), considered the last phase of Indus Valley Civilisation and beginning of the Vedic civilization. The Rigveda contains a reference to the emerging practice, in RV 10.15.14, where the forefathers "both cremated (agnidagdhá-) and uncremated (ánagnidagdha-)" are invoked.
Cremation remained common but not universal, in both ancient Greece and ancient Rome. According to Cicero, burial was considered the more archaic rite in Rome.
The rise of Christianity saw an end to cremation in Europe, though it may have already been in decline.
In early Roman Britain, cremation was usual but diminished by the 4th century. It then reappeared in the 5th and 6th centuries during the migration era, when sacrificed animals were sometimes included on the pyre, and the dead were dressed in costume and with ornaments for the burning. That custom was also very widespread among the Germanic peoples of the northern continental lands from which the Anglo-Saxon migrants are supposed to have been derived, during the same period. These ashes were usually thereafter deposited in a vessel of clay or bronze in an "urn cemetery". The custom again died out with the Christian conversion of the Anglo-Saxons or Early English during the 7th century, when Christian burial became general.
