Shakespeare has borrowed part of his matter from a novel entitled _Diana_, by the Portuguese Montemayor (1520-1562). The translation, by Bartholomew Yong, was not printed until 1598, but the preface states that it had then been completed for fully sixteen years, and manuscript copies of it had no doubt passed from hand to hand, according to the fashion of the time. On comparing the essential portion of the romance[1] with _The Two Gentlemen of Verona_, we find that Proteus's infidelity and Julia's idea of following her lover in male attire, with all that comes of it, belong to Montemayor. Moreover, in the novel, Julia, disguised as a page, is present when Proteus serenades Sylvia (Celia in the original). She also goes to Sylvia at Proteus's orders to plead his cause with her; but in the novel the fair lady falls in love with the messenger in male attire--an incident which Shakespeare reserved for _Twelfth Night_. We even find in _Diana_ a sketch of the second scene of the first act, between Julia and Lucetta, in which the mistress, for appearance' sake, repudiates the letter which she is burning to read. One or two points in the play remind us of _Lovers Labour's Won_, which Shakespeare had just completed in its original form; for example, the journey in male attire in pursuit of the scornful loved one. Many things, on the other hand, point forward to Shakespeare's later work. The inconstancy of the two men in _A Midsummer Night's Dream_ is a variation and parody of Proteus's fickleness in this play. The beginning of the second scene of the first act, where Julia makes Lucetta pass judgment on her different suitors, is the first faint outline of the masterly scene to the same effect between Portia and Nerissa in _The Merchant of Venice_. The conversation between Sylvia and Julia, which brings the fourth act to a close, answers exactly to that between Olivia and Viola in the first act of _Twelfth Night._ Finally, the fact that Valentine, after learning the full extent of his false friend's treachery, offers to resign to him his beautiful betrothed, Sylvia, in order to prove by this sacrifice the strength of his friendship, however foolish and meaningless it may appear in the play, is yet an anticipation of the humble renunciation of the beloved for the sake of the friend and of friendship, which impresses us so painfully in Shakespeare's Sonnets. In almost every utterance of the young women in this comedy we see nobility of soul, and in the lyric passages a certain pre-Raphaelite grace. Take, for example, what Julia says of her love in the last scene of the second act:--
