Claim: William Shakespeare wrote Titus Andronicus.

Like most playwrights of his period , William Shakespeare did not always write alone . A number of his surviving plays are collaborative , or were revised by others after their original composition , although the exact number is open to debate . Some of the following attributions , such as The Two Noble Kinsmen , have well-attested contemporary documentation ; others , such as Titus Andronicus , are dependent on linguistic analysis by modern scholars ; recent work on computer analysis of textual style -LRB- word use , word and phrase patterns -RRB- has given reason to believe that parts of some of the plays ascribed to Shakespeare are actually by other writers .   In some cases the identity of the collaborator is known ; in other cases there is a scholarly consensus ; in others it is unknown or disputed . These debates are the province of Shakespeare attribution studies . Most collaborations occurred at the very beginning and the very end of Shakespeare 's career .
