Etain was a fairy maiden whose beauty was so great that the Faery King Midir fell in love with her at first sight.
Fairies (variously fairy, faery, fairie or faerie) lived often 'under hill', or in enchanted woods.
I do not think I have told you that my dear teacher is reading "The Faery Queen" to me.
Like the fairies everywhere they have amours with mortals, such as that of the Queen of Faery with Thomas of Ercildoune.
She was the tutelary Goddess to the ill-fated hero Cu Chulainn; she was the Faery Queen and the Washer at the Ford.
The light names typically have "Fairy" in them and the dark names will have "Faery" in the name, to distinguish which is good and which is bad.
Those who suppose him to have studied the Faery Queen might easily be confuted, if this were the proper place for a detailed examination of the passages in which the two allegories have been thought to resemble each other.
