AR'GILLAN, a haughty, turbulent knight, born on the banks of the Trent.

ARGON AND RURO, the two sons of Annir, king of Inis-thona, an island of Scandinavia. Cor'malo, a neighboring chief, came to the island, and asked for the honor of a tournament. Argon granted the request, and overthrew him, and this so vexed Cormalo that during a hunt he shot both the brothers with his bow. Their dog Runo, running to the hall, howled so as to attract attention, and Annir, following the hound, found his two sons both dead. On his return he discovered that Cormalo had run off with his daughter. Oscar, son of Ossian, slew Cormalo in fight, and restored the daughter to her father.--_Ossian_ ("The War of Inis-thona").

Surely it is an Ariadnê.... There is dawning womanhood in every line; but she knows nothing of Naxos.--Ouidà, _Ariadnê_, i. 1.
