Date and Sources
Much Ado About Nothing marks Shakespeare's greatest achievement in comedy with As You Like It and The Twelfth Night. The date of its first performance was 1598 and it was probably printed two years later. A story by Italian author Matteo Bandello is the source of the plot (as it happened for Romeo and Juliet too). Shakespeare read Bandello in the French version by Belleforest in his Histoires Tragiques.
Themes
The central part of the action turns on two main plots: the Hero-Claudio plot, which is a conventional story belonging to the tragi-comedy type, and the Beatrice-Benedick plot, belonging to the comedy of wit. In this way we are offered differrent views of the same reality, views which we might call respectively romantic and realistic, in whose clash and interrelatio lies a great part of the substance of the play.
