"He must observe their mood on whom he jests,
The quality of persons, and the time,
And, like the haggard, check at every feather
That comes before his eye. This is a practice
As full of labour as a wise man's art."

The Clown forms a sort of connecting-link between the serious characters and the exclusively comic figures of the play—the pair of knights, Sir Toby Belch and Sir Andrew Aguecheek, who are entirely of Shakespeare's own invention. They are sharply contrasted. Sir Toby, sanguine, red-nosed, burly, a practical joker, always ready for "a hair of the dog that bit him," a figure after the style of Bellman;[2] Sir Andrew, pale as though with the ague, with thin, smooth, straw-coloured hair, a wretched little nincompoop, who values himself on his dancing and fencing, quarrelsome and chicken-hearted, boastful and timid in the same breath, and grotesque in his every movement. He is a mere echo and shadow of the heroes of his admiration, born to be the sport of his associates, their puppet, and their butt; and while he is so brainless as to think it possible he may win the love of the beautiful Olivia, he has at the same time an inward suspicion of his own stupidity which now and then comes in refreshingly: "Methinks sometimes I have no more wit than a Christian or an ordinary man has; but I am a great eater of beef, and, I believe, that does harm to my wit" (i. 3). He does not understand the simplest phrase he hears, and is such a mere reflex and parrot that "I too" is, as it were, the watchword of his existence. Shakespeare has immortalised him once for all in his reply when Sir Toby boasts that Maria adores him (ii. 3), "I was adored once too." Sir Toby sums him up in the phrase:

"For Andrew, if he were opened, and you find so much blood in his liver as will clog the foot of a flea, I'll eat the rest of the anatomy."

The central character in Twelfth Night is Viola, of whom her brother does not say a word too much when, thinking that she has been drowned, he exclaims, "She bore a mind that envy could not but call fair."

Shipwrecked on the coast of Illyria, her first wish is to enter the service of the young Countess; but learning that Olivia is inaccessible, she determines to dress as a page (a eunuch) and approach the young unmarried Duke, of whom she has heard her father speak with warmth. He at once makes the deepest impression upon her heart, but being ignorant of her sex, does not dream of what is passing within her; so that she is perpetually placed in the painful position of being employed as a messenger from the man she loves to another woman. She gives utterance to her love in carefully disguised and touching words (ii. 4):—

"My father had a daughter lov'd a man,
As it might be, perhaps, were I a woman,
I should your lordship.
Duke. And what's her history?
Vio. A blank, my lord. She never told her love,—
But let concealment, like a worm i' the bud,
Feed on her damask cheek: she pin'd in thought:
And, with a green and yellow melancholy,
She sat like Patience on a monument,
Smiling at grief."

But the passion which possesses her makes her a more eloquent messenger of love than she designs to be. To Olivia's question as to what she would do if she loved her as her master does, she answers (i. 5):—

"Make me a willow cabin at your gate,
And call upon my soul within the house;
Write loyal cantons of contemned love,
And sing them loud even in the dead of night;
Holla your name to the reverberate hills,
And make the babbling gossip of the air
Cry out, Olivia! O! you should not rest
Between the elements of air and earth,
But you should pity me."

In short, if she were a man, she would display all the energy which the Duke lacks. No wonder that, against her own will, she awakens Olivia's love. She herself, as a woman, is condemned to passivity; her love is wordless, deep, and patient. In spite of her sound understanding, she is a creature of emotion. It is a very characteristic touch when, in the scene (iii. 5) where Antonio, taking her for Sebastian, recalls the services he has rendered, and begs for assistance in his need, she exclaims that there is nothing, not even "lying vainness, babbling drunkenness, or any taint of vice," that she hates so much as ingratitude. However bright her intelligence, her soul from first to last outshines it. Her incognito, which does not bring her joy as it does to Rosalind, but only trouble and sorrow, conceals the most delicate womanliness. She never, like Rosalind or Beatrice, utters an audacious or wanton word. Her heart-winning charm more than makes up for the high spirits and sparkling humour of the earlier heroines. She is healthful and beautiful, like these her somewhat elder sisters; and she has also their humorous eloquence, as she proves in her first scene with Olivia. Yet there rests upon her lovely figure a tinge of melancholy. She is an impersonation of that "farewell to mirth" which an able English critic discerns in this last comedy of Shakespeare's brightest years.[3]
