I have drawn gratefully on the work of previous editors of this play, especially the earlier New Mermaid edition by Roma Gill, as well as the Revels edition by J. R. Mulryne, the Cambridge edition by David L. Frost, and the Penguin edition by Bryan Loughrey and Neil Taylor.
I am especially indebted to four generous colleagues – Keir Elam, Scott Cutler Shershow, James R. Siemon and David P. Young – for their assistance at various stages of this project; their wisdom and advice have been as valuable as their friendship, which is saying a great deal.
