Rituals such as widow sacrifice/widow burning have, presumably, prehistoric roots. Early 20th-century pioneering anthropologist James G. Frazer, for example, thought that the legendary Greek story of Capaneus, whose wife Evadne threw herself on his funeral pyre, might be a relic of an earlier custom of live widow-burning. In Book 10 of Quintus Smyrnaeus' Posthomerica (lines 467ff.), Oenone is said to have thrown herself on he burning pyre of her erstwhile husband Paris, or Alexander. The strangling of widows after their husbands' deaths are attested to from cultures as disparate as the Natchez people in present-day Louisiana, to a number of Pacific Islander cultures.
