Note 155 — ACT IV.
Reading edition
“The ‘Dun Cow’ is, we all know, intimately connected with the celebrated Guy, Earl of Warwick, and I believe his ‘kettle’ is one of the pretended relics still shown there. From the text I conjecture that the dun cow with the kettle on her head was in the time of Marston a well-known sign.”—Dilke.
