But mythology is of such vital need to literature that, deprived of the store of legend native to southern Europe, imaginative writers looked for a fresh impulse. They turned their eyes to the North. Inspiration was sought, not from Olympus, but from Asgard. Moreover, it was believed that the fount of primeval poetry issuing from Scandinavian and Teutonic myth was truly our own, and that we were rightful heirs of it by reason of the Anglo-Saxon in our blood. And so, indeed, we are; but it is not our sole heritage. There must also run much Celtic—that is, truly British—blood in our veins.[1] And Matthew Arnold was probably right in asserting that, while we owe to the Anglo-Saxon the more practical qualities that have built up the British Empire, we have inherited from the Celtic side that poetic vision which has made English literature the most brilliant since the Greek.[2] We have the right, therefore, to enter upon a new spiritual possession. And a splendid one it is! The Celtic mythology has little of the heavy crudeness that repels one in Teutonic and Scandinavian story. It is as beautiful and graceful as the Greek; and, unlike the Greek, which is the reflection of a clime and soil which few of us will ever see, it is our own. Divinities should, surely, seem the inevitable outgrowth of the land they move in! How strange Apollo would appear, naked among icebergs, or fur-clad Thor striding under groves of palms! But the Celtic gods and heroes are the natural inhabitants of a British landscape, not seeming foreign and out-of-place in a scene where there is no vine or olive, but “shading in with” our homely oak and bracken, gorse and heath.
