There is a lake in one of the Galtee mountains where there is a great
serpent chained to a rock, and he may be heard constantly crying out,
“O Patrick, is the _Luan_, or Monday, long from us?” For when St.
Patrick cast this serpent into the lake he bade him be chained to the
rock till _La-an-Luan_ (The Day of Judgment). But the serpent mistook
the word, and thought the saint meant _Luan_, Monday.
So he still expects to be freed from one Monday to another, and the
clanking of his chains on that day is awful to hear as he strives to
break them and get free.
In another lake there is a huge-winged creature, it is said, which
escaped the power of St. Patrick, and when he gambols in the water such
storms arise that no boat can withstand the tumult of the waves.
