It is after he leaves that Maria says of him:

—Act II, scene iii, line 140

 Maria describes the most prominent component of Malvolio's character to be a monstrous self-pride and suggests that they work up a plan to take advantage of that. She will imitate Olivia's handwriting and drop notes in places where he can find them so that he will be misled into thinking Olivia is in love with him. He will then, Maria is sure, promptly make a most enormous ass of himself.

Toby is absolutely delighted, and when she leaves, he calls after her:

—Act II, scene iii, line 177

Penthesilea in the Greek legends was an Amazon. According to some of the tales, she was the younger sister of Hippolyta, whom Theseus had married (see page I-18). It was Penthesilea who killed Hippolyta in the Amazonian war of revenge against Theseus, and afterward she joined the Trojans in their war against the Greeks and was killed in turn by Achilles.

Clearly, an Amazon is bound to be a large and muscular woman, and Penthesilea particularly so, since she fought with credit against Achilles himself. But Maria, it is clear in several places in the play, is a particularly small girl, which gives Toby's remark its humor.

Duke Orsino, who intends to continue to use Viola/Cesario as his messenger to Olivia, talks of love to the "young man." Viola/Cesario sadly tells her love to Orsino, pretending it is her sister she is speaking of, and saying:

—Act II, scene iv, lines 111-16

There is a glancing reference here to the doctrine of the four humors, first advanced by the school of Greek physicians who followed the famous Hippocrates of Cos (of the fifth century b.c.).

They believed that there were four fluids, or "humors," in the body: phlegm, blood (sanguis in Latin), bile (chole in Greek), and black bile (melanchole in Greek).

Bile is the secretion of the liver and there is only one variety, a greenish-yellow fluid. On standing, it grows much darker and becomes almost black; hence the distinction between bile and black bile.

The Greek physicians elaborated the theory that the predominance of one fluid over the other resulted in a particular type of temperament or "humor" (see page II-424). There were people who were phlegmatic, sanguine, choleric, or melancholic.

The expression "green and yellow melancholy" refers to the fact that bile was supposedly predominant in the melancholic, though Shakespeare is thinking of ordinary bile, rather than black bile.

At Olivia's house, the plot to catch Malvolio progresses. A new character enters, Fabian. He is another of Olivia's servants and he too has a grudge against Malvolio. He says:

—Act II, scene v, lines 6-7

In bearbaiting, a bear is tied to a stake, and sometimes muzzled. Dogs are then set on it and the "sport" consists in watching the maddened bear slowly tortured to death, usually killing a few dogs on the way. It was very popular in the time of Elizabeth I, and in 1575 thirteen bears were baited with the Queen an interested spectator. This "amusement" was not finally outlawed in England till 1835.

Apparently Fabian had organized a bearbaiting, and Malvolio had complained of it to Olivia, whose soft heart had been touched and who had been angry with Fabian in consequence.

This is a reflection of the fact that the Puritans, to their great credit, strove to have bearbaiting made illegal. (There were, however, not wanting those who said, cynically, that Puritans were against bearbaiting not because it gave pain to the bear but because it gave pleasure to the spectators.)

Malvolio now enters the trap. The letter has been planted in the garden, and the plotters hide in a tree watching Malvolio. The steward is so lost in self-conceit that he dreams of marriage with Olivia and begins to assume the airs of a great lord. Sir Toby is almost choked with indignation, and Sir Andrew, imitating Toby, cries out:

—Act II, scene v, line 41

Jezebel was the idolatrous Queen of Israel, wife of wicked King Ahab. She is a byword for pride. When her son (the successor of Ahab) was killed by the revolutionary general Jehu, she met the murderer in her palace as a queen should. Though facing death, she dressed herself like a queen and taunted Jehu with a past revolution that had failed. Or, as the Bible puts it (2 Kings 9:30-31), "And when Jehu was come to Jezreel, Jezebel heard of it, and she painted her face, and tired her head, and looked out at a window. And as Jehu entered in at the gate, she said, Had Zimri peace, who slew his master?"

Of course, Sir Andrew's use of the name is inappropriate from the standpoint of sex; for a man, however proud, can scarcely be a Jezebel; and his simplicity is designed to raise a laugh in the audience.

Malvolio eventually spies the letter, picks it up, and examines it. The handwriting on the outside seems Olivia's and the seal which closes the fold has Olivia's imprint. Malvolio describes it as:

—Act II, scene v, lines 94-95

A person of quality would use a particular stamp (perhaps engraved on a ring) to impress the drop of wax sealing a letter, as further indication of ownership and guard against forgery. Olivia uses a representation of the Roman matron Lucretia, concerning whom (see page I-205) Shakespeare had written The Rape of Lucrece some six or seven years before. Of course, Maria had made use of her mistress' seal.

Malvolio interprets the letter exactly as pleases his self-love. It advises him to do just the sort of thing Maria knows Olivia loathes. He is told to smile constantly, to be haughtier and surlier than ever, to talk politics, cultivate eccentricity, wear yellow stockings, and be cross-gartered. He swears to do it all, and when he leaves, Fabian, in the tree, half dead with suppressed laughter, says:
