Note to King Lear, 3.4.140: "Peace, Smulkin; peace,"

King Lear,
Act 3, Scene 4, line 140

Smulkin A devil from Samuel Harsnett's Declaration of Egregious Popish Impostures (1603); the frequent borrowings from Harsnett in King Lear (such as Flibbertigibbet, line 115, Modo and Mahu, line 144) set the earliest composition date for the play.
