Note 148 — THE BOOK OF THE DEAN OF LISMORE.

Rath Cruachan, as Irish tradition says, was the chief seat of the Feinn of Connaught, usually called the Sons of Morn. The word “Rath” means a Fort, and Cruachan an elevation more than usually steep. It sometimes stands upon another hill, as in Argyleshire, where we have “Cruachan Beinne,” The hillock upon the mountain, usually called Ben Cruachan. The word “Rath” enters largely into Scottish topography, and assumes different forms in English, as Rath, Roth, Rothie, Rait, Raits, etc.
