lifted, but Lug cast a stone at the eye, so that it was carried through his head, blasting some of his own men.23 In a ballad account of this, Balor was beheaded by Lug, but asked him to set the head upon his own and earn his blessing. Fortunately for himself, however, Lug set it on a hazel, and it dropped poison which spHt the hazel in two. The tree became the abode of vultures and ravens for many years, until Manannan caused it to be dug up, when a poisonous vapour from its roots killed and wounded many of the workmen. Of the wood Luchta made a shield for Manannan, which became one of the famous shields of Erin. It could not be touched in battle and it always caused utter rout. Finally it became Fionn's shield.24

Bres was found unguarded by Lug and others, and made three offers for his life; but two of these—that Ireland's kine should always be in milk, and that corn would be reaped every quarter—were rejected. Life was offered him, however, if he would tell how the men of Erin should plough, sow, and reap; and when Bres said that these things should always be done on a Tuesday, he was set free.25 In another account four Fomorians escaped, ruining corn, milk, fruit, and sea produce; but on November Eve (Samhain) they were expelled by Bodb, Midir, Oengus, and the Morrígan, so that never more should their depredations occur.26 This points to the conception of the Fomorians as powers of blight; that of Bres suggests rather that they were pre-Celtic gods of fertility.

Ogma captured the sword of the war-god Tethra, and when unsheathed it told the deeds it had done, as was the custom with swords in those days, for, as the Christian compiler adds, "the reason why demons spake from weapons was because weapons were then worshipped and acted as
