They possessed the following characteristics and imposed some or all of them on very different forms of drama: subjects drawn from English history, the presentation of historical and political events, an incongruous mixture of material, a narrative structure almost as unorganized as the chronicles themselves, patriotic sentiments, and the stage pageantry of court and camp. From their earliest appearance, however, the chronicle plays offered opportunities for developments later consummated by Shakespeare. Comic scenes were freely interspersed to enliven the tedium of royal declamations, and in these lay the possibility of the combination of history and comedy in the Falstaff plays. On the other hand, the history of a doleful fall of a prince or the retribution visited on some tyrant gave the plays a tragic tone and opened the way for "Macbeth" and "Lear." "The Troublesome Reign of King John,"[9] the basis of Shakespeare's play, is the best example of an early chronicle play presenting undeveloped possibilities for tragedy. It is written partly in blank verse, partly in rhyme, and partly in prose. It does not follow the chronicles with any fidelity, but twists history, adds fiction, and proclaims throughout a vigorous protestant patriotism. Battles, embassies, farce, orations, death, and much else mingle together, each scene being treated like another and no discernible method being followed in their arrangement or proportion, except that of a loose adherence to the scheme of "a life and death." The first part closes with John crowned and assured of the miscarriage of his intended murder of Arthur; in the second part, as the address to the reader declares, "First scenes shows Arthur's death in infancie, And last concludes John's fatall tragedie." "The Troublesome Reign" indicates what little advance had been made toward tragedy when Marlowe's first play appeared. The prologue to that play was a declaration of reform and innovation. "From jigging veins of rhyming mother wits, And such conceits as clownage keeps in pay, We'll lead you to the stately tent of war, Where you shall hear the Scythian Tamburlaine Threatening the world with high astounding terms, And scourging kingdoms with his conquering sword." The doggerel rhyme favored in the popular drama was to give place to blank verse, and the jigging clowns to heroic themes and "high astounding terms." Marlowe came to the theatre,[10] fresh from the university, his fancy aflame with the beauty of Latin verse and story, his mind storming with the problems and ambitions of adolescent genius. He threw aside Senecan traditions and devoted himself to meeting the demands of the professional stage. When a few years later he died, English tragedy had been created anew largely through his achievement.
