The first recorded works of Shakespeare are Richard III and the three parts of Henry VI, written in the early 1590s during a vogue for historical drama. Shakespeare's plays are difficult to date precisely, however,^[86] and studies of the texts suggest that Titus Andronicus, The Comedy of Errors, The Taming of the Shrew, and The Two Gentlemen of Verona may also belong to Shakespeare's earliest period.^[87] His first histories, which draw heavily on the 1587 edition of Raphael Holinshed's Chronicles of England, Scotland, and Ireland,^[88] dramatise the destructive results of weak or corrupt rule and have been interpreted as a justification for the origins of the Tudor dynasty.^[89] The early plays were influenced by the works of other Elizabethan dramatists, especially Thomas Kyd and Christopher Marlowe, by the traditions of medieval drama, and by the plays of Seneca.^[90] The Comedy of Errors was also based on classical models, but no source for The Taming of the Shrew has been found, though it is related to a separate play of the same name and may have derived from a folk story.^[91] Like The Two Gentlemen of Verona, in which two friends appear to approve of rape,^[92] the Shrew's story of the taming of a woman's independent spirit by a man sometimes troubles modern critics and directors.^[93]
