The three witches are characters in William Shakespeare’s Macbeth, often referred to as “the Scottish play” in the world of theatre. A possible source of inspiration for these characters the three Fates of Greek mythology, who control the life of every mortal from birth to death: one spinning the metaphorical thread of life, one measuring its length and one cutting it at the allotted time.
Speak, if you can: what are you?
All hail, Macbeth! hail to thee, thane of Glamis!
All hail, Macbeth, hail to thee, thane of Cawdor!
All hail, Macbeth, thou shalt be king hereafter!
Shakespeare Macbeth Act I, Scene (ii)
