d. But Manannan suddenly
appears, reawakens Fand's love, and she departs with him. The god shakes
his cloak between her and Cuchulainn to prevent their ever meeting
again.[1237] In this story Labraid, Fand, and Liban, Fand's sister,
though dwellers on an island Elysium, are called _sid_-folk. The two
regions are partially confused, but not wholly, since Manannan is
described as coming from his own land (Elysium) to woo Fand. Apparently
Labraid of the Swift Hand on the Sword (who, though called "chief of the
_side_", is certainly a war-god) is at enmity with Manannan's hosts, and
it is these with whom Cuchulainn has to fight.[1238]

In an Ossianic tale several of the Fians were carried off to the Land of
Promise. After many adventures, Fionn, Diarmaid, and others discover
them, and threaten to destroy the land if they are not restored. Its
king, Avarta, agrees to the restoration, and with fifteen of his men
carries the Fians to Erin on one horse. Having reached there, he bids
them look at a certain field, and while they are doing so, he and his
men disappear.[1239]

3. _Land under Waves._--Fiachna, of the men of the _sid_, appeared to
the men of Connaught, and begged their help against Goll, who had
abducted his wife. Loegaire and his men dive with Fiachna into Loch
Naneane, and reach a wonderful land, with marvellous music and where the
rain is ale. They and the _sid_-folk attack the fort of Mag Mell and
defeat Goll. Each then obtains a woman of the _side_, but at the end of
a year they become homesick. They are warned not to descend from
horseback in Erin. Arrived among their own people, they describe the
marvels of Tir fa Tonn, and then return there, and are no more
seen.[1240] Here, again, the _sid_ Elysium and Land under Waves are
confused, and the divine tribes are at war, as in the story of
Cuchulainn.

In a section of the Ossianic tale just cited, Fionn and his men arrive
on an island, where Diarmaid reaches a beautiful country at the bottom
of a well. This is Tir fa Tonn, and Diarmaid fights its king who has
usurped his nephew's inheritance, and thus recovers it for him.[1241]

4. _Co-extensive with this world._--An early example of this type is
found in the _Adventures of Cormac_. A divine visitant appeared to
Cormac and gave him in exchange for his wife, son, and daughter, his
branch of golden apples, which when shaken produced sweetest music,
dispelling sorrow. After a year Cormac set out to seek his fami
