Olivia's love for Viola/Cesario does not go unnoticed, however. The foolish Sir Andrew is not so foolish as to fail to see it, and, petulantly, he decides his own suit is useless and prepares to leave.
Toby and Fabian, unwilling to let go their profitable gull, try to argue him out of this first sensible decision he has made. They assure him that Olivia is only trying to make him jealous and that Sir Andrew is losing out only because he isn't a daring enough lover. Sir Toby says:
—Act III, scene ii, lines 26-30
To sail into the north of a lady's opinion is a clear metaphor representing her growing coldness. It is also a topical reference. Between 1594 and 1597 there was the most spectacular attempt man had yet seen to explore the Arctic regions. The Dutch explorer Willem Barents had sailed northeastward, discovering Spitsbergen in 1596 and exploring the coasts of the large Siberian islands of Novaya Zemlya. He spent the whiter of 1596-97 in the Arctic, the first non-Eskimo to do so. He died in 1597 on his return voyage and in his honor that stretch of water lying between Spitsbergen and Novaya Zemlya is known as the Barents Sea. There is no doubt but that the "Dutchman" in Sir Toby's speech is a reference to Barents.
Given the choice between valor and policy, Sir Andrew (equally pathetic in both) chooses valor as the manlier. He says:
—Act III, scene ii, lines 32-33
This is another sneer at Puritanism. The Brownists were followers of Robert Browne, who was such an extreme Puritan he felt he had to leave the Church of England altogether. He founded an independent church hi 1580 and in 1582 went off into exile to the Netherlands.
The Brownists were to form an interesting part of American history. Some of them, who had made a new home for themselves in Dutch exile, felt they could not maintain their English identity there and determined to establish a colony in the New World. In 1620, four years after Shakespeare's death, they sailed westward and landed in Plymouth, becoming America's revered Pilgrim Fathers.
Pleased with Sir Andrew's decision to be valiant, Sir Toby mischievously urges him on to write a challenge to Viola/Cesario. He tells him to write
—Act III, scene ii, lines 47-49
Ware was a market town about twenty miles north of London which in Shakespeare's time was famous for a huge bed, eleven feet square, reportedly capable of allowing twelve people to sleep on it at once. It was in several different inns in the vicinity at one time or another and in 1931 finally came into the possession of the Victoria and Albert Museum in London.
This new practical joke has scarcely been placed under way when the old one regarding Malvolio reaches a climax. Maria comes in to say that Malvolio has fulfilled all the requests of the letter; yellow stockings, cross-garterings, and all, down to the perpetual smiling: 588 ITALIAN
—Act III, scene ii, lines 78-80
Mariners were particularly interested in marking a rhumb line on a map that would indicate the shortest distance from one point to another. On the globe, such a line would be a curve spiraling northward or southward.
In 1568 the Flemish geographer Gerhard Kremer (better known by the Latinized version of his last name, Mercator) put out a map of the world plotted in such a way that the rhumb lines were straight. Maps for navigation based on Mercator's scheme could be easily marked with rhumb lines, and many of them were therefore put in, crossing and crisscrossing.
What's more, the sixteenth-century explorations had led to an increasingly detailed knowledge of the Americas ("The Indies"), and about the time that Twelfth Night was being written, a new map, with numerous rhumb lines, was published, showing the New World in far greater and more accurate detail than had ever been shown before. This added detail was the "augmentation of the Indies."
Maria tells Olivia that Malvolio seems to be raving, and when he appears on the scene, grotesquely clothed and quoting meaningfully from the letter, Olivia, flabbergasted, can only think he really is mad.
Malvolio is so far gone in self-delusion, however, that he interprets everything in the light of Olivia's supposed love for him, and in the midst of his triumphing, he remembers to be pious, saying:
—Act III, scene iv, lines 87-88
This is undoubtedly intended to mock Puritan sanctimoniousness, and, just as undoubtedly, the real Malvolio would have said "God" or "the Lord" or "the Almighty." Growing Puritan strength, however, in later years clamped down on references to God on the stage, and this form of ridiculous censorship led to the foolish substitution of "Jove."
Sir Toby conies fussing in, full of mock concern over Malvolio's madness, and saying:
—Act III, scene iv, lines 89-92
This is a reference to one of the examples of demonic possession in the New Testament. When Jesus asks the name of the "unclean spirit" possessing a man, that spirit answers "My name is Legion: for we are many" (Mark 5:9).
Toby baits Malvolio with his supposed madness and when the latter rushes off in a fury, Toby arranges to have him placed in a dark room because of his supposed madness, so that the practical joke may continue.
Meanwhile the affair of Sir Andrew and Viola/Cesario is developing further. Sir Andrew has written a cautiously phrased and clearly cowardly letter. Sir Toby accepts it gravely, but does not deliver it. He intends to deliver a challenge verbally, enormously exaggerating Sir Andrew's fire-eating propensities. He will then report with equal exaggeration to Sir Andrew, concerning what a raging fury Viola/Cesario is in. He says:
