Phantom Islands

The world of 18th century pirates was filled with ghosts, sea monsters, and even Phantom Islands. A phantom island is a supposedly real island that appeared on maps for a period of time (sometimes centuries) during recorded history, but was later proven not to exist.

The most famous phantom island is probably Atlantis. This large island (or small continent, depending on who you listen to) was first recorded by the ancient Greek philosopher Plato. He claimed that Atlantis was located “past the pillars of Hercules” – in other words, outside the familiar Mediterranean Sea, in the wide ocean that was eventually named after it.

Plato was trying to make a point about pride. His story tells of a technologically advanced society that fell out of favor with the gods because of the arrogance of its leaders. In his story, Atlantis eventually sank beneath the waves.

This mythical place inspired the name of the Atlantic Ocean, and other imaginary islands have inspired names for real land forms. One is Brasil or Hy-Brasil, an island traditionally believed to lay off the west coast of Ireland. Supposedly, it was shrouded in mist, and could only be seen once every seven years. When explorers saw the South American mainland rising out of the morning mists, they must have thought of Ireland’s imaginary twin.

How do the stories of Phantom Islands begin?

Sometimes, they are started by mirages. Just as the desert can provide images of water to travelers, the sea can offer up imaginary lands. Temperature inversions – layers of warm air laying above cooler air – can actually bend light, making a small object appear to be a towering mass. These kinds of inversions are rare, but can give a definite impression of land.

Another way that a phantom island can be recorded is that the explorer is simply lost. This happened a lot more 300-500 years ago. Misplaced travelers saw Greenland, or Africa, or Japan, when they believed they were far away from those locations, and thought they’d found something new. This is probably the origin of St Mathew Island, said to lie off the coast of Africa. Sailors who reported seeing it were probably looking at Ascension Island, which really does exist.

Once an island had been put on a map, there was social pressure for voyagers to confirm its existence. A sailor stands in a bar (or an officer stands before his superiors) and tells a tale of his travels. “Oh, you were near Saint Brendan’s Isle!” says someone. “Did you see it?”

What’s a man to do? “Of course I saw it!”

Some phantoms, such as Saxemberg Island, may have actually existed. It was discovered in 1670, and spotted again in 1804, 1809, and 1816, always in exactly the same location. This island is so well reported that it may have once existed… A piece of land that sank under the sea in some volcanic event.

Plenty of real things have been mistaken for islands. Ice bergs, fog banks, floating masses of seaweed (especially with the help of temperature inversions that makes them seem mountainous.)  Antarctica has inspired several phantoms, The Terra Nova islands, for instance, were discovered in  near Antarctica 1968, and haven’t been seen since.

Some phantoms are philosophical construction. Rupes Nigra was an island invented in the 14th century   to explain why compasses point north. Since no one yet knew about the Earth’s magnetic poles, someone invented a magnetic, black island at the exact place we now call magnetic north.

Some phantoms islands were deliberate fabrications. When money is involved, all things are possible. Croakerland, for instance, was a hoax invented by the famous Arctic explorer, Robert E. Peary, to gain more financial aid from one of his financial bankers, George Crocker. And Isles Phelipeaux and Pontchartrain were invented in the Great Lake Superior in 1744 to persuade French financial backers to cough up more money for further explorations in the area.

But there are plenty of honest explorers out there, too. Johan Otto Polter, found an island he named Kantia. In 1884. But when he returned later, in four expeditions through 1909, he failed to find it again, and disproved the island's existence.

Map of The Island of California

One of the most famous cartographical errors in history is the description of California as an island. This may have been inspired by fiction. A 1510 Spanish romance novel Las sergas de Esplandián by Garci Rodríguez de Montalvo - described the island in this passage:

Actual Strait of Baja

 Know, that on the right hand of the Indies there is an island called California very close to the side of the Terrestrial Paradise; and it is peopled by black women, without any man among them, for they live in the manner of Amazons.

Men love those sex-starved Amazons. Whether it was this titillating tale, or an offer by the King of Spain that explorers could lay claim to any new islands they found, but could not similarly profit from discoveries of new sections of mainland, California was shown as an island for nearly 200 years.

Maybe not what they had in mind
Which leads us to one of the most enduring parts of Phantom Islands… their tendency to endure. Once put onto a chart, the predisposition is for the island to stay put. After all, to erase it is, in effectively call its discoverer either a liar or a fool. So, even today, a few unlikely islands and reefs still endure. Once such is Yosemite Rock, “discovered” in 1903, and supposed to be approximately 83°W, 32°S (Northwest of Robinson Crusoe Island). With all our technology, it’s never been officially disproved. Instead, in the Operational Navigation Chart of the United States Department of Defense it is listed as "Existence doubtful."
