Note 2 — THE LEGEND OF KNOCKFIERNA.[2] II.
Reading edition
“Called by the people of the country ‘Knock Dhoinn Firinne,’ the mountain of Donn of Truth. This mountain is very high, and may be seen for several miles round; and when people are desirous to know whether or not any day will rain, they look at the top of Knock Firinne, and if they see a vapour or mist there, they immediately conclude that rain will soon follow, believing that Donn (the lord or chief) of that mountain and his aërial assistants are collecting the clouds, and that he holds them there for some short time, to warn the people of the approaching rain. As the appearance of mist on that mountain in the morning is considered an infallible sign that that day will be rainy, Donn is called ‘Donn Firinne,’ Donn of Truth.”—Mr. Edward O’Reilly.
