Fourteen Lines

The melancholy Dane consumed with spite;
The daughter from King Cymbeline's first wife;
A brother from The Tempest and Twelfth Night;
The passion of poor Silvius's life;
Who steals away young Jessica's dear heart;
The Moor who's bringing Titus an untruth;
The prefix setting Siward's son apart;
The Prince of Wales who drinks away his youth;
The King of Fairies ruling the wood;
The King of Ithica who fought in Troy;
Beware the fortune teller (Caesar should);
The bastard son of Gloucester, evil boy;
Initial letters of these names suggest;
Their author's information I request;
