hamlet

We know that there was an older play by Thomas Kyd, that extraordinary dramatic (if not poetic) genius who was in all probability the author of two plays so dissimilar as the Spanish Tragedy and Arden of Feversham; and what this play was like we can guess from three clues: from the Spanish Tragedy itself, from the tale of Belleforest upon which Kyd's Hamlet must have been based, and from a version acted in Germany …

…very strong show of reason, that the original play of Kyd was, like certain other revenge plays, in two parts of five acts each. The upshot of Mr. Robertson's examination is, we believe, irrefragable: that Shakespeare's Hamlet, so far as it is Shakespeare's, is a play dealing with the effect of a mother's guilt upon her son, and that Shakespeare was unable to impose this motive successfully upon the "intractable" material of the old play.
