The Third Folio was issued in 1663, published by Philip Chetwinde; Chetwinde had married Robert Allot's widow and so obtained the rights to the book. To the second impression of the Third Folio (1664) he added seven plays, namely "Pericles, Prince of Tyre;" "Locrine;" "The London Prodigal;" "The Puritan;" "Sir John Oldcastle;" "Thomas Lord Cromwell;" and "A Yorkshire Tragedy." (See: Shakespeare Apocrypha.) All seven of these additional plays had been published as quartos while Shakespeare was alive, but only "Pericles" was eventually widely accepted into the Shakespearean canon.
