<b>Cymbeline by William Shakespeare</b> -&nbsp;<i><b>Cymbeline</b></i>&nbsp;/'s?mb?li?n/, also known as&nbsp;<i><b>The Tragedie of Cymbeline</b></i>&nbsp;or&nbsp;<i><b>Cymbeline, King of Britain</b></i>, is a play by&nbsp;William Shakespeare&nbsp;set in&nbsp;Ancient Britain&nbsp;(c.&thinsp;10&ndash;14)[a]&nbsp;and based on legends that formed part of the&nbsp;Matter of Britain&nbsp;concerning the early Celtic British King&nbsp;Cunobeline. Although it is listed as a tragedy in the&nbsp;First Folio, modern critics often classify&nbsp;<i>Cymbeline</i>&nbsp;as a&nbsp;romance&nbsp;or even a&nbsp;comedy.<br /><br />Like&nbsp;<i>Othello</i>&nbsp;and&nbsp;<i>The Winter&#39;s Tale</i>, it deals with the themes of innocence and jealousy. While the precise date of composition remains unknown, the play was certainly produced as early as 1611.<br /><br />Cymbeline, the&nbsp;Roman Empire&#39;s vassal king of Britain, once had two sons, Guiderius and Arvirargus, but they were stolen 20 years earlier as infants by an exiled traitor named Belarius. Cymbeline discovers that his only child left, his daughter Imogen (or Innogen), has secretly married her lover Posthumus Leonatus, a member of Cymbeline&#39;s court.<br /><br />The lovers have exchanged jewellery as tokens: Imogen with a bracelet, and Posthumus with a ring. Cymbeline dismisses the marriage and banishes Posthumus since Imogen &mdash; as Cymbeline&#39;s only child &mdash; must produce a fully royal-blooded heir to succeed to the British throne. In the meantime, Cymbeline&#39;s Queen is conspiring to have Cloten (her cloddish and arrogant son by an earlier marriage) married to Imogen to secure her bloodline. The Queen is also plotting to murder both Imogen and Cymbeline, procuring what she believes to be deadly poison from the court doctor. The doctor, Cornelius, is suspicious and switches the poison for a harmless sleeping potion.
