This play exists in two forms: the published quarto, 1606, and a manuscript (Folger Shakespeare Library MS. V.a.55) that supplies some useful alternative readings, many of which are adopted in J. B. Leishman's diplomatic edition of the Parnassus sequence. Leishman proposes that the quarto and the MS were both derived from an earlier MS itself (T1) derived from the original text, and that a further MS (T2) was intermediary between T1 and the Folger MS. According to the title-page of the quarto, the play was "Publiquely acted by the Students in St. Iohns Colledge in Cambridge," very probably in 1601. Extensive speculation about the authorship has produced no consensus.
