t or _Lodens Lamargentios_ represents
_Nodens_ (Nuada) _L[=a]margentios_, the change being the result of
alliteration, has been contested,[409] while if the Welsh Lludd and Nudd
were identical it is strange that they should have become distinct
personalities, Gwyn, son of Nudd, being the lover of Creiddylad,
daughter of Lludd,[410] unless in some earlier myth their love was that
of brother and sister. Lludd is also confused or is identical with Llyr,
just as the Irish Ler is with Alloid. He is probably the son of Beli
who, in the tale of _Lludd and Llevelys_, by the advice of Llevelys rids
his country of three plagues.[411] These are, first, the Coranians who
hear every whisper, and whom he destroys by throwing over them water in
which certain insects given him by Levelys have been bruised. The second
is a shriek on May-eve which makes land and water barren, and is caused
by a dragon which attacks the dragon of the land. These Lludd captures
and imprisons at Dinas Emreis, where they afterwards cause trouble to
Vortigern at the building of his castle. The third is that of the
disappearance of a year's supply of food by a magician, who lulls every
one to sleep and who is captured by Lludd. Though the Coranians appear
in the _Triads_ as a hostile tribe,[412] they may have been a
supernatural folk, since their name is perhaps derived from _cor_,
"dwarf," and they are now regarded as mischievous fairies.[413] They may
thus be analogous to the Fomorians, and their story, like that of the
dragon and the magician who produce blight and loss of food, may be
based on older myth or ritual embodying the belief in powers hostile to
fertility, though it is not clear why those powers should be most active
on May-day. But this may be a misunderstanding, and the dragons are
overcome on May-eve. The references in the tale to Lludd's generosity
and liberality in giving food may reflect his function as a god of
growth, but, like other euhemerised gods, he is also called a mighty
warrior, and is said to have rebuilt the walls of Caer Ludd (London),
his name still surviving in "Ludgate Hill," where he was buried.[414]
This legend doubtless points to some ancient cult of Lludd at this spot.

Nudd already discussed under his title Nodons, is less prominent than
his son Gwyn, whose fight with Gwthur we have explained as a mythic
explanation of ritual combats for the increase of fertility. He also
appears as a hunter and as a great warrior,[415]
