Note 16 — Darthool and the Sons of Usna
Reading edition
In old Irish Gaelic, Derdriu, then Deirdrê, sometimes Darethra. In Scotland, Dearduil (pronounced Dart’weel, Darth-uil, or “Darthool,” whence Macpherson’s “Darthula,” who rather loosely says the name is Dart’huile, a woman of beautiful eyes). The oldest name is said to signify alarm.
