Although most editions of this play credit William Shakespeare on the title page, it is in fact by William Rowley (ob. 1626) as shown by the 1622 entry in Sir Henry Herbert's office-book (isbn 0198122462, page 136). The coupling of Shakespeare's name with Rowley's on the title page of the first edition (1662), based on a late and often inaccurate bookseller's catalogue is probably a ploy to help sales.
