As various nuts and fruits were prized in Ireland as food, and were perhaps used in some cases to produce an intoxicant,[1277] it is evident that the trees of Elysium were, primarily, a magnified form of earthly trees. But all such trees were doubtless objects of a cult before their produce was generally eaten; they were first sacred or totem-trees, and their food eaten only occasionally and sacramentally. If so, this would explain why they grew in Elysium and their fruit was the food of the gods. For whatever man eats or drinks is generally supposed to have been first eaten and drunk by the gods, like the soma. But, growing in Elysium, these trees, like the trees of most myths of Elysium, are far more marvellous than any known on earth. They have branches of silver and golden apples; they have magical supplies of fruit, they produce wonderful music which sometimes causes sleep or oblivion; and birds perch in their branches and warble melody “such that the sick would sleep to it.” It should be noted also that, as Miss Hull points out, in some tales the branch of a divine tree becomes a talisman leading the mortal to Elysium; in this resembling the golden bough plucked by AEneas before visiting the underworld.[1278] This, however, is not the fundamental characteristic of the tree, in Irish story. Possibly, as Mr. A.B. Cook maintains, the branch giving entrance to Elysium is derived from the branch borne by early Celtic kings of the wood, while the tree is an imaginative form of those which incarnated a vegetation spirit.[1279] Be this as it may, it is rather the fruit eaten by the mortal which binds him to the Immortal Land.
