But perhaps the best way to get a full sense of the storied antiquity, forming as it were the background to those mediæval documents which in Mr. Nash’s eyes pretty much begin and end with themselves, is to take, almost at random, a passage from such a tale as _Kilhwch and Olwen_, in the _Mabinogion_,—that charming collection, for which we owe such a debt of gratitude to Lady Charlotte Guest (to call her still by the name she bore when she made her happy entry into the world of letters), and which she so unkindly suffers to remain out of print. Almost every page of this tale points to traditions and personages of the most remote antiquity, and is instinct with the very breath of the primitive world. Search is made for Mabon, the son of Modron, who was taken when three nights old from between his mother and the wall. The seekers go first to the Ousel of Cilgwri; the Ousel had lived long enough to peck a smith’s anvil down to the size of a nut, but he had never heard of Mabon. ‘But there is a race of animals who were formed before me, and I will be your guide to them.’ So the Ousel guides them to the Stag of Redynvre. The Stag has seen an oak sapling, in the wood where he lived, grow up to be an oak with a hundred branches, and then slowly decay down to a withered stump, yet he had never heard of Mabon. ‘But I will be your guide to the place where there is an animal which was formed before I was;’ and he guides them to the Owl of Cwm Cawlwyd. ‘When first I came hither,’ says the Owl, ‘the wide valley you see was a wooded glen. And a race of men came and rooted it up. And there grew a second wood; and this wood is the third. My wings, are they not withered stumps?’ Yet the Owl, in spite of his great age, had never heard of Mabon; but he offered to be guide ‘to where is the oldest animal in the world, and the one that has travelled most, the Eagle of Gwern Abwy.’ The Eagle was so old, that a rock, from the top of which he pecked at the stars every evening, was now not so much as a span high. He knew nothing of Mabon; but there was a monster Salmon, into whom he once struck his claws in Llyn Llyw, who might, perhaps, tell them something of him. And at last the Salmon of Llyn Llyw told them of Mabon. ‘With every tide I go along the river upwards, until I come near to the walls of Gloucester, and there have I found such wrong as I never found elsewhere.’ And the Salmon took Arthur’s messengers on his shoulders up to the wall of the prison in Gloucester, and they delivered Mabon.
