Brobdingnag is a fictional land in Jonathan Swift's satirical novel Gulliver's Travels occupied by giants. Lemuel Gulliver visits the land after the ship on which he is travelling is blown off course and he is separated from a party exploring the unknown land. Apparently this name is a typo, as in the book prologue Gulliver calls it Bodingrag.

The adjective Brobdingnagian has come to describe anything of colossal size.

Swift describes the location of Brobdingnag, and its geography, in the text of Part II of Gullivers Travels, and provides a map showing where it is. However these accounts are somewhat contradictory.

The map printed at the beginning of Part II indicates that Brobdingnag is located on the northwest coast of North America. It shows (from south to north) Point Monterey, Port Sir Francis Drake, Cape Mendocino, Cape St Sebastian, Cape Blanco and the semi-mythical Strait of Anián, all locations on the Pacific coast of North America, and depicts Brobdingnag as a peninsula extending west into the Pacific to the north of the Straits.

In the book Gulliver describes his voyage from England. After wintering at the Cape of Good Hope, the ship reached a latitude of five degrees south, northward of Madagascar in March 1703, and the Moluccas, "about three degrees northwards of the line" in April. From there the ship is driven by a storm "about five hundred leagues to the east" (this would place the ship still in Micronesia), after which the crew determine to "hold on the same course rather than turn more northerly, which might have brought us to the north-west parts of Great Tartary. They sighted land, which Gulliver later discovers is Brobdingnag, on 16 June 1703.

Brobdingnag is claimed to be a continent-sized peninsula six thousand miles long and three thousand miles wide, which based on the location given by Gulliver would suggest that it covers most of the North Pacific. Contrariwise, his map shows Brobdingnag to be of a similar size and extent as the present-day Washington, and his description of the voyage puts it at a six week voyage from the Moluccas.

Swift was highly sceptical about the reliability of travel writings and the unlikely geographic descriptions parody many unreliable travel books published at the time which Percy Adams describes as "travel lies".[1]


Unlike his account of Lilliput, Gulliver does not say exactly how big the people of Brobdingnag are. However, in at least two cases he states explicitly that a Brobdingnagian's eyes are "above sixty feet" from the ground, giving a ratio of at least eleven to one. He also states that he would "appear as inconsiderable to this nation as a Lilliputian would be among us", suggesting the same twelve to one ratio given for Lilliput was intended. Gulliver also describes visiting the chief temple in Lorbrulgrud, whose tower was the highest in the kingdom, but reports he “came back disappointed, for the height is not above three thousand foot", which "allowing for the difference in size between those people and us in Europe” is “not equal in proportion to Salisbury steeple”.


Brobdingnag is said to be located between Japan and California, extending six thousand miles in length, and between three and five thousand miles in breadth. It is described as a peninsula, terminated to the northeast by a range of volcanoes up to 30 miles (48 km) high separating the country from unknown land beyond. It is surrounded on three other sides by the ocean, and the people have never been able to develop ocean-going ships. The land "has 51 cities, near 100 walled towns, and a great number of villages". Lorbrulgrud is claimed to be the capital with the king having a seaside palace at Flanflasnic. The capital "contains above 80,000 houses" and "is in length three glonglungs (about fifty four English miles) and two and a half in breadth". Gulliver tells us that Lorbrulgrud was “situated near the middle of that empire” and was three thousand miles distant from the farmers house on the coast, that the journey took ten weeks and that they “crossed five or six rivers many degrees broader and deeper than the Nile or the Ganges”, and “there was hardly a rivulet smaller than the Thames at London Bridge”.

Flora and fauna

The people of Brobdingnag are described as giants who are as tall as a church steeple and whose stride is ten yards. All of the other animals and plants, and even natural features such as rivers and even hail, are in proportion. The rats are the size of mastiffs, with tails "two yards long, wanting an inch", while mastiffs are "equal in bulk to four elephants". Gulliver describes flies "as big as a Dunstable lark", and wasps the size of partridges, with stings "an inch and a half long, and sharp as needles". This also means that the country is far more dangerous for people of normal human size, as evidenced by Gulliver using his hanger far more often here—namely, on attacking vermin—than in any other of the strange countries he visited; fortunately for Gulliver, the people are civilised. A splacknuck is an animal about 6 feet (1.8 m) long, to which Gulliver is compared in size, although it is never explained which animal it corresponds to (probably a rodent of some sort, such as a rat). Fossil records are claimed to show that the ancestors of the Brobdingnagians were once even larger, but it is possible scholars have misidentified the fossils as human, which happened in Europe as well at the time.[2] The King of Brobdingnag argues that the race has deteriorated.

History and government

The King of Brobdingnag and Gulliver (1803), Metropolitan Museum of Art

Gulliver relates that, in the past, there were battles between the monarchy, nobility, and people resulting in a number of civil wars ending in a treaty. The monarchy is based on reason. The King of Brobdingnag finds English institutions and behaviour wanting in comparison with his country's. Based on Gulliver's descriptions of their behaviour, the King describes the English as "the most pernicious race of little odious vermin that nature ever suffered to crawl upon the surface of the earth."[3] Swift intended the moral relationship between the English and Brobdingnagians to be as disproportionate as the physical relationship. The King of Brobdingnag is considered to be based on Sir William Steele, a statesman and writer, whom Swift worked for early in his career.

The army of Brobdingnag is claimed to be large with 207,000 troops including 32,000 cavalry although the society has no known enemies. The local nobility commands the forces; firearms and gunpowder are unknown to them. The King scolds Gulliver when he tries to interest the statesman in the use of gunpowder.

The laws of Brobdingnag are simple and easy to follow. There is little civil litigation. Murderers are beheaded.

Note also that in Gulliver's in-character preface to the story, headed A letter from Captain Gulliver to his cousin Sympson, he specifies that the correct spelling is in fact "... Brobdingrag (for so the word should have been spelt, and not erroneously Brobdingnag), ... [emphasis added]". This correction by the fictional author is a device used to add an element of verisimilitude to the story.


Brobdingnagian culture consists of history, poetry, mathematics and ethics, mathematics being a particular strength. Printing has been long known but libraries are relatively small. The king has the largest library, which contains about one thousand volumes. The Brobdingnagians favour a clear literary style.
