Phantom Islands
Phantom islands are islands that were believed to exist, and appeared on maps for a period of time (sometimes centuries) during recorded history, but were later removed after they were proved to be nonexistent. Phantom islands usually stem from the reports of early sailors exploring new realms. Some arose through the mislocation of actual islands; errors in geography; navigational errors; the misidentification of icebergs, fog banks, or to optical illusions. Other ”errors” were later thought to be intentional, probably for financial gain in some way or another. [Source]
The image is of a 1623 map depicting an island called Brasil, or Hy-Brazil, just off the West coast of Ireland. Like many other phantom islands, the cartographic existence of Hy-Brasil was based on a combination of flimsy legend, faulty observations, wishful thinking, and outright mendacity. Its first recorded appearance on a map dates from around 1325. Sometimes fantasy became indistinguishable from fact: Hy-Brasil was rumoured to be continuously obscured by mist, except for one day every seven years. It must have been on one of those days in 1674 that captain John Nisbet, piercing a sea fog, anchored before the island, and sent a party of four ashore. The amazed sailors spent an entire day on Hy-Brasil, meeting an wizened old man who provided them with gold and silver. A follow-up expedition by a captain Alexander Johnson also found Hy-Brasil, and confirmed captain Nisbet’s findings. But thereafter, Hy-Brasil reverted to its elusive self. [Source]
![This is A New Map of England and France: The French Invasion, or John Bull Bombarding the Bum-Boats, a 1793 cartographic masterpiece that depicts an anthropomorphic Britain launching a tidal wave of feces across the English Channel at would-be French invaders and revolutionists.
This piece was drawn by English caricaturist James Gillray, who made his career on thousands of satirical cartoons. This map was Gillray’s response to growing revolutionary zeal on the Continent. Explains the British Museum of this piece:
A comic map […] is represented by the body of George III (John Bull), his head in profile to the right, wearing a fool’s cap composed of ‘Northumberland’. His left leg is drawn up, Norfolk forms the knee, the mouth of the ‘River Thames’ the ankle, Kent the foot. His outstretched right leg terminates as Cornwall. From the coast, at the junction of ‘Hampshire’ and ‘Sussex’, issues a blast of excrement inscribed ‘British Declaration’, which smites a swarm of ‘Bum-Boats’ extending from Ushant to the mouth of the Seine. The map is divided (inaccurately, and with omissions, but with a rough correctness) into counties, Wales representing the flying coat-tails of the King, who strides across the ocean with great vigour.](http://25.media.tumblr.com/tumblr_m9c54xTwQp1rnseozo1_1280.jpg)
