FATA MORGANA: can we believe our eyes?

 

A Fata Morgana (Italian: [ˈfaːta morˈɡaːna]) is an unusual and complex form of superior mirage that is seen in a narrow band right above the horizon. It is the Italian name for the Arthurian sorceress Morgan le Fay, from a belief that these mirages, often seen in the Strait of Messina, were fairy castles in the air or false land created by her witchcraft to lure sailors to their deaths. 

Although the term Fata Morgana is sometimes applied to other, more common kinds of mirages, the true Fata Morgana is different from both an ordinary superior mirage and an inferior mirage.

Fata Morgana mirages significantly distort the object or objects on which they are based, often such that the object is completely unrecognizable.

A Fata Morgana can be seen on land or at sea, in polar regions or in deserts. It can involve almost any kind of distant object, including boats, islands and the coastline.

A Fata Morgana is often rapidly changing. The mirage comprises several inverted (upside down) and erect (right side up) images that are stacked on top of one another. Fata Morgana mirages also show alternating compressed and stretched zones.

BLOGSERVATIONS. I knew something about mirages, but I thought they were those things in the desert, where you see water and palm trees on the horizon and by the time you run to them, they're gone. But the Fata Morgana, named after the sorceress Morgan Le Fay in the Arthurian legend, is something quite else.

I seem to remember, in certain films, seeing something above the water, something weirdly shimmering that kept changing size and shape. It seemed to melt, stretch and reform like a strange liquid. Sometimes you could see through it. These things likely freaked out those sailors of antiquity, just as they freak out people today. Pirate ship? Imminent attack? One can see where they might be mistaken for a UFO.

A boat can suddenly project itself upward so that it appears to hang in the sky, morphing from an elongated shape to a blob to - nothing. The marine mirages make sense - sort of - because of all that reflection on the water. But what about the ones on land?

Wikipedia tells me (and how can Wikipedia be wrong?) that a Fata Morgana can be almost anything: an island, a mountainside, a mountain GOAT if you could get a goat to hang upside-down. But how about whole cities? The photos from China appear to show tall buildings supended above the clouds, leading a lot of people to cry "photoshop!" Then how to explain the video of the same phenomenon? Who could have created that?

All this comes from the Land of the Strange, that country in which I am a cliffdweller or sharecropper or part-time lover. It's all very well to say "it's just a trick of light". Simple physics. Physics is a strange thing, however, and some time I'll post something about the overtone chanting of Tibetan monks, which is, quite literally, a chord coming from one person's throat. The way the sound leaps all over the musical spectrum is downright spooky, and seems impossible.

Do we believe our eyes, and if we don't, what do we rely on? Physics? Upside-down boats (or goats), or castles in the air? And did anyone in that eerie floating city in China happen to look down?

Fata Morgana of a distant rock

A Fata Morgana is something that isn't. Like a mirage, it's a trick of light and atmosphere, usually seen over water, but more elaborate than that. Mountains turn into boats and then majestic castles, then just sort of erode away, so you are not sure which image was real. I don't think I've ever seen one except in a movie. It's one of those sights which likely evoked terror in ancient humans, when no one understood why an entire ship was hanging upside-down fifty feet above the surface of the water. And why that same ship then slowly turned inside-out and sank into the ocean.

In every video of a Fata Morgana I could find, there is a big argument in the comments section about whether it is a Morgana or (in fact) a mirage. I don't care. It's a weird, cool, slightly spooky thing, a thing we can clearly see but which actually doesn't exist in the form we're seeing. Who or what is playing this eerie trick of distortion on our eyes and brain?


I use this video not so much because it's a good example (though it is that), but because of the beautiful noise of the surf, the utter lack of captions, and the beach-dwellers casually romping while the bizarre illusion plays out in the distance. The gifs were just lying around in my file, left over from another post.
