Mr. W. St. Chad Boscawen, in his learned lecture on "A Chaldean Heliopolis," at Manchester, in December, 1881, after referring to the manner in which Berosus "had resort to an ingenious literary fiction to preserve the continuity of the narrative in his history of Chaldea, which he claimed to have based on documentary evidence, extending back over fifteen myriads of years," says--"The daily recurring war of day and night, which had belonged to the nomadic age, now became national wars and combats of Samson, Shamgar, and Gideon, the solar heroes, against the dark forces of the Philistine and Midianite. But in this period of the heroic age--the 'once upon a time' of the Chaldean story-teller, the nation was not one consolidated whole; it was the age of polyarchy. The beginning of Nimrod's kingdom was not one capital city, it was the tetrapolis of Babel, Akkad, Erech, and Calrech, and each city was a little kingdom. So each city had its hero. The giant Isdubar was the hero of Erech; Sargon the Moses of Chaldea--the hero of Aganne; Etanne and Ner, of Babylon. In the labours and wars of these heroes we saw the labours and wars and struggles of the city kingdom, but lit with the lustre of divinity which shone forth from the age of the gods and clothed with its brightness the characters in the heroic age. But, in time, as the nation became consolidated, all became blended and absorbed into the great national hero, Isdubar, the great king." The Rev. Sir G. W. Cox, in his "Mythology of the Aryan Nations," successfully shows that the principal materials of the Arthurian legends are identical with those which underlie the Hindoo, Grecian, Teutonic, and other common Aryan myths. He contends that Arthur is a solar hero, of the same type as Phoibus Chrysâôr, or Heracles, or Bellerophon, or Perseus, or Achilleus, or Sigurd; and he illustrates this position by the citation of numerous instances in which their common original is clearly perceptible, notwithstanding the great modification, especially in costume and morals, to which the original materials have been subjected. A single instance of this uniformity, but an important one, will suffice for the present purpose. The peculiar form as well as the name of the supernatural weapon of Indra, the Vedic _lightning_ god, has undergone many changes in its progress through the mythical lore of the various Aryan nations, and yet its identity is rarely, if ever, doubtful. It is the "Durandal" of Roland; it is Arthur's famous sword "Excalibur," as well as the similar weapon which no one could draw from the "iron anvil-sheaf embedded in stone" except himself. It is the sword of the maiden drawn by Balin, after Arthur had failed in the attempt. It is the "Macabuin," the weapon of the Manx hero, Olave of Norway; it is Odin's sword "Gram," stuck in the roof-tree of Volsung's hall. It is the sword of Chrysâôr; it is that of Theseus, and that of Sigurd. It is very
