Of these plays perhaps "Locrine"[12] has the most diverse indebtedness. It presents a story of a bloody family feud, but it is also of the chronicle history order, with a mixture of battles, patriotism, and farce. It exhibits borrowings from Spenser, imitations of "Tamburlaine," Ate as a chorus, dumb shows requiring a menagerie, two ghosts, one of whom takes part in the action, and a story of double revenge. The hero is occupied with revenge number one until the fourth act, when his infidelity makes him the object of a return revenge that culminates in his death. Among the plays mainly indebted to Marlowe are: Greene's "Alphonsus of Aragon," a comedy that is almost a travesty on the first part of "Tamburlaine"; "Selimus," ascribed to Greene, which also shows Senecan structure and philosophy; "The Wounds of Civil War, or the Tragedies of Marius and Sylla," the first extant play based on Plutarch; "The Wars of Cyrus," in part romantic comedy; and Peele's "Battle of Alcazar," which has a presenter, dumb shows, three ghosts, and a Moorish villain of the same class as Marlowe's Barabas and Aaron in "Titus Andronicus." The English chronicle plays also felt Marlowe's influence, most notably in Shakespeare's early historical plays, to be considered in a moment, but also in several plays almost contemporary with "Edward II" and the first versions of "Henry VI." "The True Tragedy of Richard III" (1594), by an unknown author or authors, seems to have preceded Shakespeare's play and to have followed the third part of "Henry VI." It presents a combination of chronicle play with Marlowesque protagonist and a Kydian apparatus of revenge. The ghost of Clarence appears at the beginning crying, "Vindicta," and Truth and Poetry supply the necessary exposition. The revenge element becomes prominent toward the end of the play, when the ghosts of Richard's victims appear to him in a dream, not visible as in Shakespeare, and the remorseful villain declares that not merely his victims but all the forces of nature, sun, moon, and planets, cry revenge:-- "The birds sing not, but sorrow for revenge. The silly lambs sit bleating for revenge."
