Irish: Happiness; Mab was known as the fairies'' midwife, but she delivered dreams, not children.
"O, then, I see Queen Mab hath been with you.
She is the fairies’ midwife, and she comes
In shape no bigger than an agate-stone
On the fore-finger of an alderman" —Mercutio to Romeo in Shakespeare''s tragedy, Romeo and Juliet.
