A sarcophagus (plural, sarcophagi) is a coffin for a mummy, most commonly carved in stone, and usually displayed above ground, though it may also be buried. The word "sarcophagus" comes from the Greek σάρξ sarx meaning "flesh", and φαγεῖν phagein meaning "to eat", hence sarcophagus means "flesh-eating"; from the phrase lithos sarkophagos (λίθος σαρκοφάγος). Since lithos is Greek for "stone", lithos sarcophagos means "flesh-eating stone". The word also came to refer to a particular kind of limestone that was thought to rapidly facilitate the decomposition of the flesh of corpses contained within it due to the chemical properties of the limestone itself.
Sarcophagi were most often designed to remain above ground. In Ancient Egypt, a sarcophagus acted like an outer shell.
The Hagia Triada sarcophagus is a stone sarcophagus elaborately painted in fresco; one style of later Ancient Greek sarcophagus in painted pottery is seen in Klazomenian sarcophagi, produced around the Ionian Greek city of Klazomenai, where most examples were found, between 550 BC (Late Archaic) and 470 BC. They are made of coarse clay in shades of brown to pink. Added to the basin-like main sarcophagus is a broad, rectangular frame, often covered with a white slip and then painted. The huge Lycian Tomb of Payava, now in the British Museum, is a royal tomb monument of about 360 BC designed for an open-air placing, a grand example of a common Lycian style.
Ancient Roman sarcophagi—sometimes metal or plaster as well as limestone—were popular from about the reign of Trajan, and often elaborately carved, until the early Christian burial preference for interment underground, often in a limestone sepulchre, led to their falling out of favor. However, there are many important Early Christian sarcophagi from the 3rd to 4th centuries.
Most Roman examples were designed to be placed against a wall and are decorated on three of the sides only. Sarcophagi continued to be used in Christian Europe for important figures, especially rulers and leading church figures, and by the High Middle Ages often had a recumbent tomb effigy lying on the lid. More plain sarcophagi were placed in crypts, of which the most famous examples include the Habsburg Imperial Crypt in Vienna, Austria. The term tends to be less often used to describe Medieval, Renaissance, and later examples.
In the early modern period, lack of space tended to make sarcophagi impractical in churches, but chest tombs or false sarcophagi, empty and usually bottomless cases placed over an underground burial, became popular in outside locations such as cemeteries and churchyards, especially in Britain in the 18th and 19th centuries, where memorials were mostly not highly decorated and the extra cost of a false sarcophagus over a headstone acted as an indication of social status.
Sarcophagi, usually "false", made a return to the cemeteries of America during the last quarter of the 19th century, at which time, according to a New York company which built sarcophagi, "it was decidedly the most prevalent of all memorials in our cemeteries". They continued to be popular into the 1950s, at which time the popularity of flat memorials (making for easier grounds maintenance) made them obsolete. Nonetheless, a 1952 catalog from the memorial industry still included 8 pages of them, broken down into Georgian and Classical detail, a Gothic and Renaissance adaptation, and a Modern variant. Shown on the right are sarcophagi from the late 19th century located in Laurel Hill Cemetery in Philadelphia, Pennsylvania. The one in the back, the Warner Monument created by Alexander Milne Calder (1879), features the spirit or soul of the deceased being released.
In the Mekong Delta in southwestern Vietnam, it is common for families to inter their members in sarcophagi near their homes, thus allowing ready access for visits as a part of the indigenous tradition of ancestor worship.
Nearly 140 years after British archaeologist Alexander Rea unearthed a sarcophagus from the hillocks of Pallavaram in Tamil Nadu, an identical artifact dating back by more than 2,000 years has been discovered in the same locality. The details may be found in the following link:

- WordInfo etymology. As a noun the Greek term was further adopted to mean "coffin" and was carried over into LATIN, where it was used in the phrase lapis sarcophagus, "flesh-eating stone", referring to those same properties of limestone.
