With the third we tread on surer ground. No event in the history of these lands is better known than the fight on the Braavalla Heath, in Östergothland, where the blind old king, Harald Hildetand, met his fate in the year 736, or 750 according to others. As the Saga tells us, Odin had, when the king was young, taught him a form of tactics which gave him a superiority in battle over all his enemies; but the god having withdrawn his favour from him, he fell before the prowess of his nephew, Sigurd Ring, to whom the god had communicated the secret of the battle array. It does not appear to admit of doubt that the circles shown in the cut in the opposite page were erected to commemorate this event, and that they contain the bodies of those who were slain in this action; and if this is so, it throws considerable light on the battle-fields of Moytura, illustrated woodcuts Nos. 54 to 61. The circles on Braavalla are generally from 20 to 40 feet in diameter, and consequently are, on the average, smaller than those at Moytura; they are also more numerous, unless we adopt Petrie's suggestion,[327] that there must originally have been at least two hundred in the Irish field; and if so, it is the smaller ones that would certainly be the first to be cleared away, so that the similarity may originally have been greater than it now is--so great, indeed, as to render it difficult to account for the fact that two battle-fields should have been marked out in a manner so similar when so long a time as seven centuries had elapsed between them. As it does not appear possible that the date of the Braavalla fight can be shifted to the extent of fifty years either way, are we deceiving ourselves about Moytura? Is it possible that it represents some later descent of Scandinavian Vikings on the west coast of Ireland, and that the cairn on Knocknarea-- "High and broad, By the sailors over the waves To be seen afar, The beacon of the war renowned"[328]-- which they built up during ten days--is really the grave of some Northern hero who fell in some subsequent fight at Carrowmore? That all these are monuments of the same class, and belong, if not to the same people, at least to peoples in close contact with one another, and having similar faiths and feelings, does not appear to admit of doubt. When, however, we come to look more closely at them, there are peculiarities about them which may account for even so great a lapse of time. The Braavalla circles are smaller, and on the whole perhaps, we may assume, degenerate. There are square and triangular graves, and other forms, which, so far as we know, are comparatively modern inventions, and, altogether, there are changes which may account for that lapse of time; but that more than seven centuries elapsed between the two seems to be most improbable.
