A coffin is a funerary box used for viewing or keeping a corpse, either for burial or cremation.
Coffins are sometimes referred to as a casket, particularly in American English. Any box in which the dead are buried is a coffin, and while a casket was originally regarded as a box for jewelry, use of the word "casket" in this sense began as a euphemism introduced by the undertaker's trade. A distinction is commonly drawn between "coffins" and "caskets", using "coffin" to refer to a tapered hexagonal or octagonal (also considered to be anthropoidal in shape) box and "casket" to refer to a rectangular box, often with a split lid used for viewing the deceased as seen in the picture. Receptacles for cremated and cremulated human ashes (sometimes called cremains) are called urns.
First attested in English in 1380, the word coffin derives from the Old French cofin, from Latin cophinus, which means basket, which is the latinisation of the Greek κόφινος (kophinos), basket. The earliest attested form of the word is the Mycenaean Greek ko-pi-na, written in Linear B syllabic script.
The modern French form, couffin, means cradle.
The earliest evidence of wooden coffin remains, dated at 5000 BC, was found in the Tomb 4 at Beishouling, Shaanxi. Clear evidence of a rectangular wooden coffin was found in Tomb 152 in an early Banpo site. The Banpo coffin belongs to a four-year-old girl; it measures 1.4 m (4.6 ft) by 0.55 m (1.8 ft) and 3–9 cm thick. As many as 10 wooden coffins have been found at the Dawenkou culture (4100–2600 BC) site at Chengzi, Shandong. The thickness of the coffin, as determined by the number of timber frames in its composition, also emphasized the level of nobility, as mentioned in the Classic of Rites, Xunzi and Zhuangzi. Examples of this have been found in several Neolithic sites: the double coffin, the earliest of which was found in the Liangzhu culture (3400–2250 BC) site at Puanqiao, Zhejiang, consists of an outer and an inner coffin, while the triple coffin, with its earliest finds from the Longshan culture (3000–2000 BC) sites at Xizhufeng and Yinjiacheng in Shandong, consists of two outer and one inner coffins.
