What is the author's style in Edward II: The Troublesome Reign and Lamentable End of Edward the Second, King of England, with the Tragical Fall of Proud Mortimer by Christopher Marlowe?

Blank verse, unrhymed lines with a measured rhythm, was not invented by Christopher Marlowe, but he is credited with having instituted its use in English drama. The rhythm usually takes the form of iambic pentameter, ten syllables with the accent falling on every other syllable. Marlowe's blank verse demonstrates how the measure can be varied, using slight variations in accenting or in the placement of pauses (caesura) to retain the freshness of normal speech, while maintaining the formality of poetry. Because of its great flexibility, it is a medium that lends itself perfectly to the expression of natural sentences: "Here, take my crown, the life of Edward too, / Two kings in England cannot reign at once." Although balanced by the rhythm, these two lines also contain the spontaneity of unrehearsed speech. In the hands of Shakespeare, the same form became even more elastic: "For God's sake, let us sit upon the ground / And tell sad stories of the deaths of kings ..." {Richard II). Marlowe freed dramatic lyrics from the constraints of rhyming lines, thus paving the way for further lyric innovations. By taking greater liberties with the stresses but holding to the overall rhythm of iambic pentameter, Shakespeare produced his psychologically realistic plays, as he let his characters express even more realistic utterances than Marlowe was able to achieve.
