A play called _Cardenno_, or _Cardenna_, was acted at Court by Shakespeare's company in 1613. It is thought that this play was the _History of Cardenio_, described as "by Fletcher and Shakespeare," which was licensed for publication in 1653 but never published. The play is now lost. It was attributed to Fletcher and Shakespeare on very poor authority.
_Arden of Feversham_ is a domestic tragedy founded on a story told by Holinshed. It was published anonymously in 1592. It is held by some to be an early work of Shakespeare's, on the ground that no other known poet, then living, could have written it. It is a strong play, but it is the work of a joyless mind. It bears no single trace of Shakespeare's mind. It could not have been written by him at any stage in his career.
_Edward III_ is an historical chronicle play by at least two unknown hands. It was published anonymously in 1596. Some think that part of Act I and the whole of Act II (dealing with the King's obsession of passion for the Countess of Salisbury) were by Shakespeare, on the grounds that the writing is too good to be by anybody else then living, and that the unknown author makes use of a line and a phrase which occur in the genuine sonnets of Shakespeare. The scenes attributed to Shakespeare contain several beautiful lines in something of the Shakespearean manner. The construction of the scenes, and their relation to the rest of the play is un-Shakespearean. It is unlikely that Shakespeare wrote them.
_The Spanish Tragedy_, a play by Thomas Kyd, published in 1592 and reprinted with many additions ten years later, contains in the additions several magnificent scenes of the passion of grief raised to madness. Some think that Ben Jonson wrote these scenes; others, that they are too good to be by any one but Shakespeare. They are not like Shakespeare's work.
_The Two Noble Kinsmen_, a romantic tragedy on the subject of Chaucer's _Knight's Tale_, was first published in 1634. It was described on the title-page as the joint work of Fletcher and Shakespeare. Shakespeare's hand is plainly marked upon the play; but it seems likely that most of the scenes usually credited to him are by Massinger. Few can have ears dull enough to credit Shakespeare with all the scenes that are plainly not by Fletcher.
