Computer Analysis Confirms Shakespeare as Principal Author of Edward III, with Marlowe as Co-Writer

publication · 2026-10-20

A study conducted by Dr. Rory Loughnane and Brett Greatley-Hirsch has established that William Shakespeare is the main author of the 1596 play Edward III, with Christopher Marlowe serving as a collaborator. Their analysis, which compared the play to works by ten different playwrights, identified 23 sections as Shakespeare's and nine as Marlowe's. Loughnane, affiliated with the University of Kent, and Greatley-Hirsch from the University of Leeds, propose that their partnership began in 1592, prior to Marlowe's death in 1593. The research, which examines linguistic characteristics, attributes a speech in scene 13 to Shakespeare and the final scene's dialogue to Marlowe. Results will appear in Shakespeare Quarterly, and Loughnane's book, Shakespeare at Thirty, is set for release this week. An exhibition dedicated to Marlowe is ongoing until 22 November.
