The small cohort of contrarian scholars who traffic in conspiracy theories about “who really wrote” the plays of William Shakespeare has been joined by two luminaries of the British stage — Sir Derek Jacobi and Mark Rylance — along with 285 other skeptics, who recently signed a Declaration of Reasonable Doubt About the Identity of William Shakespeare, the BBC reported yesterday.

The declaration, which is sponsored by the Shakespeare Authorship Coalition, takes no position on who wrote the masterpieces of English drama if Shakespeare himself did not. It merely cites what it characterizes as the skimpy evidence to support Shakespeare’s authorship, and asserts, not very trippingly on the tongue, that mainstream scholars should allow the issue to be the subject of research and discussion — without smirking.

The skeptics also cite a panoply of literary lights, including Charlie Chaplin and Sigmund Freud, who expressed doubt that Shakespeare was Shakespeare. After that lengthy exegesis, it’s unclear whether the skeptics are gilding the lily or just protesting too much. Regardless, they will have some difficulty persuading the virtually unanimous chorus of literary scholars who have dismissed the so-called “authorship question” as nonsense. —Andrew Mytelka
