Edmund (King Lear) Edmund (King Lear) Edmund or Edmond is a fictional character and the main antagonist in William Shakespeare's "King Lear". He is the illegitimate son of the Earl of Gloucester, and the younger brother of Edgar, the Earl's legitimate son. Early on in the play, Edmund resolves to get rid of his brother, then his father, and become Earl in his own right. He later flirts with both Goneril and Regan and attempts to play them off against each other. Shakespeare's source for the subplot of Edmund, Edgar and Gloucester was a tale from Philip Sidney's "Countess of Pembroke's Arcadia" of
King Lear in "King Lear". Other possible sources are the anonymous play "King Leir" (published in 1605); "The Mirror for Magistrates" (1574), by John Higgins; "The Malcontent" (1604), by John Marston; "The London Prodigal" (1605); Montaigne's "Essays", which were translated into English by John Florio in 1603; "An Historical Description of Iland of Britaine" (1577), by William Harrison; "Remaines Concerning Britaine" (1606), by William Camden; "Albion's England" (1589), by William Warner; and "A Declaration of egregious Popish Impostures" (1603), by Samuel Harsnett, which provided some of the language used by Edgar while he feigns madness. "King Lear" is also a literary variant
