The cause of the marked change from Mycenaean inhumation to Homeric cremation is matter of conjecture. It has been suggested that burning was introduced during the migrations after the Dorian invasion. Men could carry the ashes of their friends to the place where they finally settled. [Footnote: Helbig, _Homerische Epos,_ p.83] The question may, perhaps, be elucidated by excavation, especially in Asia Minor, on the sites of the earliest Greek colonies. At Colophon are many cairns unexplored by science. Mr. Ridgeway, as is well known, attributes the introduction of cremation to a conquering northern people, the Achaeans, his "Celts." It is certain that cremation and urn burial of the ashes prevailed in Britain during the Age of Bronze, and co-existed with inhumation in the great cemetery of Hallstatt, surviving into the Age of Iron. [Footnote: Cf. _Guide to Antiquities of Early Iron Age,_ British Museum, 1905, by Mr. Reginald A. Smith, under direction of Mr. Charles H. Read, for a brief account of Hallstatt culture.] Others suppose a change in Achaean ideas about the soul; it was no longer believed to haunt the grave and grave goods and be capable of haunting the living, but to be wholly set free by burning, and to depart for ever to the House of Hades, powerless and incapable of hauntings. It is never easy to decide as to whether a given mode of burial is the result of a definite opinion about the condition of the dead, or whether the explanation offered by those who practise the method is an afterthought. In Tasmania among the lowest savages, now extinct, were found monuments over cremated human remains, accompanied with "characters crudely marked, similar to those which the aborigines tattooed on their forearms." In one such grave was a spear, "for the dead man to fight with when he is asleep," as a native explained. Some Tasmanian tribes burned the dead and carried the ashes about in amulets; others buried in hollow trees; others simply inhumed. Some placed the dead in a hollow tree, and cremated the body after lapse of time. Some tied the dead up tightly (a common practice with inhumation), and then burned him. Some buried the dead in an erect 'posture. The common explanation of burning was that it prevented the dead from returning, thus it has always been usual to burn the bodies of vampires. Did a race so backward hit on an idea unknown to the Mycenaean Greeks? [Footnote: Ling Roth., _The Tasmanians_, pp. 128-134. Reports of Early Discoverers.] If the usual explanation be correct--burning prevents the return of the dead--how did the Homeric Greeks come to substitute burning for the worship and feeding of the dead, which had certainly prevailed? How did the ancient method return, overlapping and blent with the method of cremation, as in the early Dipylon interments? We can only say that the Homeric custom is definite and isolated, and that but slight variations occur in the methods of Homeric burial.
