This explains the success and fascination of that highly popular genre of island stories in the fifteenth and sixteenth centuries, which provide a record of all the islands in the world—known islands as well as those about which there were just a few vague legends. The island stories, in their own way, provided as much geographical accuracy as possible (unlike the tales of fabulous lands in earlier centuries) and were a blend of folk tales and traveler’s accounts. Sometimes they were wrong. It was thought, for example, that there were two islands, Taprobane and Ceylon, whereas in fact (as we know) there was just one—but so what? They represented a geography of the unknown or, at least, the little-known.

  Later came the journals of the eighteenth-century travelers—Cook, Bougainville, La Pérouse . . . They too were looking for islands but were careful to describe only what they saw, no longer relying on folk traditions—and that was quite a different matter. But still they went off looking for islands that didn’t exist, such as Terra Australis (which appeared on all atlases), or for an island that someone had once discovered but had never been found again.

  This is why, still today, our fantasies drift between the myth of an island that doesn’t exist, or the myth of absence; that of one island too many, or the myth of excess; that of the undiscovered island, or the myth of inaccuracy; or that of the un-rediscovered island, or the myth of the insula perdita, the lost island—four quite different stories.

  The first is a legendary story. Legends about islands are generally divided into those that require us to pretend the island exists (asking us to suspend our belief)—as with the islands of Verne or Stevenson—and those that describe an island that does not exist by definition and have the sole purpose of reaffirming the power of legends—as with Peter Pan’s Neverland. The island that, by definition, does not exist is of no interest to us, at least today. The reason is simple: no one goes looking for it—children don’t go to sea looking for Captain Hook’s island, nor do adults go in search of Captain Nemo’s island.

  Likewise, I will pass over the one island too many, not least because there is, I believe, only one case of this phenomenon of excess—the duplication of Ceylon and Taprobane. This story has been told in much detail in an article on island stories by Tarcisio Lancioni1 to which I refer you. In fact, what interests me today is that unfortunate love for an island that can no longer be found, whereas Taprobane was always being found, even when no one was looking for it, and therefore, in terms of sexual exploits, we might say it was not so much a story of hopeless passion as one of Don Giovanni–like incontinence, where the number of maps showing Taprobane had already reached mille e tre.

  According to Pliny, Taprobane was discovered during the time of Alexander the Great, and prior to that had been generally indicated as the land of the Antichthones and considered “another world.” Pliny’s island could be identified as Ceylon, and this can be seen from Ptolemy’s maps, at least in the sixteenth-century editions. Isidore of Seville also places it to the south of India and confines himself to saying that it is full of precious stones and has two summers and two winters each year. Marco Polo’s Travels doesn’t give the name Taprobane but refers to Ceylon as Seilam.

  The duplication of Ceylon and Taprobane appears quite clearly in Mandeville’s Travels, which describes them in two different chapters. He doesn’t say exactly where Ceylon is located but states that it is “well a 800 miles about” and is

  full of serpents, of dragons and of cockodrills, that no man dare dwell there. These cockodrills be serpents, yellow and rayed above, and have four feet and short thighs, and great nails as claws or talons. And there be some that have five fathoms in length, and some of six and of eight and of ten. And when they go by places that be gravelly, it seemeth as though men had drawn a great tree through the gravelly place. And there be also many wild beasts, and namely of elephants. In that isle is a great mountain. And in mid place of the mount is a great lake in a full fair plain; and there is great plenty of water. And they of the country say, that Adam and Eve wept upon that mount an hundred year, when they were driven out of Paradise, and that water, they say, is of their tears; for so much water they wept, that made the foresaid lake. And in the bottom of that lake men find many precious stones and great pearls. In that lake grow many reeds and great canes; and there within be many cocodrills and serpents and great water-leeches. And the king of that country, once every year, giveth leave to poor men to go into the lake to gather them precious stones and pearls, by way of alms, for the love of God that made Adam. And all the year men find enough. And for the vermin that is within, they anoint their arms and their thighs and legs with an ointment made of a thing that is clept lemons, that is a manner of fruit like small pease; and then have they no dread of no cockodrills, ne of none other venomous vermin . . . In that country and others thereabout there be wild geese that have two heads. (The Travels of Sir John Mandeville, chapter 21)

  Taprobane, on the other hand, according to Mandeville, is under the rule of Prester John. Mandeville had not yet sited Prester John’s realm in Ethiopia, as he would later do, and it was still in the area of India—though Prester John’s India was often confused with the farthest Orient, the land of earthly paradise. In any event, Taprobane is to be found in the vicinity of India (and he names the point where the Red Sea flows into the ocean). Like Isidore’s account, the island has two summers and two winters and there are enormous mountains of gold guarded by pismires, or giant ants:

  These pismires be great as hounds, so that no man dare come to those hills for the pismires would assail them and devour them anon. So that no man may get of that gold, but by great sleight. And therefore when it is great heat, the pismires rest them in the earth, from prime of the day into noon. And then the folk of the country take camels, dromedaries, and horses and other beasts, and go thither, and charge them in all haste that they may; and after that, they flee away in all haste that the beasts may go, or the pismires come out of the earth. And in other times, when it is not so hot, and that the pismires rest them not in the earth, then they get gold by this subtlety. They take mares that have young colts or foals, and lay upon the mares void vessels made there-for; and they be all open above, and hanging low to the earth. And then they send forth those mares for to pasture about those hills, and with-hold the foals with them at home. And when the pismires see those vessels, they leap in anon: and they have this kind that they let nothing be empty among them, but anon they fill it, be it what manner of thing that it be; and so they fill those vessels with gold. And when that the folk suppose that the vessels be full, they put forth anon the young foals, and make them to neigh after their dams. And then anon the mares return towards their foals with their charges of gold. (The Travels of Sir John Mandeville, chapter 33)

  From this point onward, from one map to the next, Taprobane moves about from one place in the Indian Ocean to another, sometimes alone, sometimes duplicating Ceylon. For a certain period it is identified with Sumatra, but sometimes we find it between Sumatra and Indochina, close to Borneo.

  Thomas Porcacchi, in Isole più famose del mondo (1572), tells us about a Taprobane full of riches, about its elephants and its immense turtles, as well as the characteristic attributed by Diodorus Siculus to its inhabitants—a kind of forked tongue (“double as far as the root and divided; with one part they talk to one person, with the other they talk to another”).

  After having recounted various folk stories, he then apologizes to readers for the fact that he has found no exact reference as to its geographical position, and concludes, “Although many ancient and modern writers have referred to this island, I find no one however who indicates its boundaries: hence I too will have to be excused if in this my usual order is lacking.” As for the island of Taprobane’s identification with Ceylon, he is doubtful: “She was first (according to Ptolemy) called Simondi, and then Salice, and finally Taprobane; but people nowadays conclude that today she is called Sumatra, though there are also those according to whom Taproba
ne is not Sumatra but the island of Zeilam . . . But some people now suggest that none of the ancients have positioned Taprobane correctly: indeed they hold that where they have put it there is no island at all that can be believed to be that.”

  From being one island too many, Taprobane therefore slowly became an island that doesn’t exist. Thomas More would treat it thus when he situated his Utopia “between Ceylon and America,” and Tommaso Campanella was to use Taprobane as the place where he built his City of the Sun.

  Let us now turn to islands whose absence has encouraged (sometimes sporadic) research and an enduring nostalgia.

  Ancient epics, of course, tell us about islands that may or may not have existed, so that the isles visited by Ulysses have produced a scholarly literature aimed at establishing which actual places they refer to. And the myth of Atlantis has led to an investigation that is not yet over (judging from the number of mystery magazines and second-rate television programs). But Atlantis was regarded rather more as an entire continent, and the idea was immediately accepted that it had sunk into the sea. It is therefore the subject of legend rather than research.

  Navigatio Sancti Brendani was perhaps the first account of the quest for an island.

  Saint Brendan and his mystical mariners visited many: the island of birds, the island of hell, the island reduced to a rock on which Judas is chained, and that bogus island that had already deceived Sinbad, on which Brendan’s ship lands—not until the following day, when the ship’s crew light fires and see the island stir in annoyance, do they realize it is not an island but a terrible sea monster called Jasconius.

  But the island that excited the imagination of those in later times is the Isle of the Blessed, a sort of earthly paradise on which our mariners land after seven years of adventure:

  A land more precious than all the others for its beauty, for the marvelous and gracious and agreeable things within it, such as its beautiful and clear and precious rivers with waters most sweet and fresh and gentle, and trees most precious in every way with precious fruits, and many roses and lilies and flowers and violas and herbs and all things sweet-smelling and perfect in their bounty. And there were songbirds of every agreeable nature and all sang harmoniously in sweet and gentle song: and the climate seemed truly agreeable like sweet springtime. And there were roads and paths of every kind, precious stones, and there was so much good that greatly cheered the heart of all those who saw it with their own eyes, and there were tame and wild animals of every kind, and they moved about and lived at their own ease and as they pleased, and lived together in domesticity without wishing to cause any harm or disturbance to the other; and there were birds of the same kind who lived together similarly. And there were vineyards and pergolas always well supplied with fine grapes that its goodness and beauty exceeded all others.

  The island paradise visited by Saint Brendan awakens a desire (something that hadn’t happened with Atlantis, Ogygia, or the island of the Phaeacians). Throughout the Middle Ages and during the Renaissance there is a firm belief that it exists. It appears on maps, such as the Ebersdorf globe. On a map prepared by Toscanelli for the king of Portugal, it appears in the middle of the sea, toward Japan, to be reached buscando el levante por el poniente, approaching the East via the west—and lies almost prophetically where America would later be discovered.

  It is sometimes on the same latitude as Ireland, though on more modern maps the island moves farther south to the latitude of the Canaries or the Fortunate Isles, and sometimes the Fortunate Isles are confused with the island called Saint Brendan. Sometimes it is identified with Madeira and sometimes with another nonexistent island such as the mythical Antillia, as it was called in the sixteenth-century Arte del navegar by Pedro da Medina. In Martin Behaim’s globe of 1492 it was positioned much farther west, close to the equator. And it now had the name Lost Island, Insula Perdita.

  Honorious of Autun, in his De imagine mundi (twelfth century), had described it as the most pleasant of islands, unknown to humans, which even when it had been found, had not been found (“Est quaedam Oceani insula dicta Perdita, amoenitate et fertilitate omnium rerum prae cunctis terris praestantissima, hominibus ignota. Quae aliquando casu inventa, postea quaesita non est inventa, et ideo dicitur Perdita”); and in the fourteenth century, Pierre Bersuire spoke in the same terms about the Fortunate Isles.

  It is apparent from the Treaty of Évora of June 1519 that the Lost Island was expected to be rediscovered one day. Under the treaty, King Manuel I of Portugal passed all rights over the Canary Isles to Spain, and the terms of the treaty expressly included a Lost or Hidden Isle. In 1569, Gerardus Mercator still marked the mysterious island on his map, and in 1721 the last explorers set off in search of it.2

  Saint Brendan’s island is not an island that doesn’t exist—someone has actually been there, but it is lost since no one has succeeded in returning to it. For this reason it becomes the subject of an unfulfilled desire and its story is an allegory of every real love story, the story of a Brief Encounter, of a mystical Doctor Zhivago who has lost his Lara. The agony of love is not the love we dream of that never happens (the island that we know doesn’t exist, the illusion of love for adolescent lovers), but the love that, having once happened, then vanishes forever.

  But how did islands come to be lost?

  From earliest antiquity, ships had no points of reference other than the stars. Using instruments like the astrolabe or the cross-staff, sailors could fix the height of a star from the horizon and calculate the distance from the zenith point; once they knew the declination, they knew on what parallel they were, given that the zenith distance plus or minus declination gives latitude. They therefore knew how far north or south they were from a given point. But to get back to an island (or any other point) the latitude was not enough—the longitude was also needed. We know that New York and Naples are on the same latitude but we also know they are not in the same place—their longitude is different and they are therefore on a different degree of the meridian.

  And this is the problem that navigators faced until almost the end of the eighteenth century. There were no certain means for determining longitude, for saying how far east or west they were from a given point.

  This is what happened with the Solomon Islands (an extraordinary example of insulae perditae). Álvaro de Saavedra Cerón went in search of these legendary islands in 1528, hoping to find King Solomon’s gold, but was sailing about between what are now called the Marshall and the Admiralty Islands. Álvaro de Mendaña arrived there, however, in 1568 and christened the Solomon Islands. But, after that, no one managed to find them again, not even Mendaña himself when he went back with Queiros, almost thirty years later, in search of them, though he only just missed them, landing instead on the island of Santa Cruz, to the southeast.

  And the same happened to others after him. The Dutch set up their East Indies Company at the beginning of the seventeenth century and created the city of Batavia in Asia as a point of departure for many eastbound expeditions. They landed at a place they called New Holland, but never reached the Solomon Islands. Other lands, probably to the east of the Solomon Islands, were similarly discovered by English pirates whom the Court of Saint James hastened to reward with noble titles. But no one was able to find any trace of the Solomon Islands, and for a long time many believed them to be only a legend.

  Mendaña had landed on them but had incorrectly fixed their longitude. And even if, through some celestial guidance, he had managed to fix them correctly, then other navigators looking for that longitude (and he himself on his second voyage) could not be entirely sure of their own longitude.

  For several centuries the great European maritime powers strove to discover a way of establishing the fixed point—the punto fijo that Cervantes had joked about—and were prepared to pay enormous sums to anyone who found an effective method. Navigators, men of science, and cranks came up with all kind of answers—there was the method based on lunar eclipses, one that examined the vari
ations of a magnetized needle, and the loch, or Dutchman’s log method; Galileo proposed a technique based on the eclipses of the satellites of Jupiter, which are so frequent that they can be seen several times each night.

  But all turned out to be inadequate. There would, of course, have been one sure method: to keep a clock on board that tells the time at one known meridian, then to find out the time at place X at sea and, by working on the basis that the globe has been subdivided since antiquity into 360 degrees of longitude and that the sun moves 15 degrees in one hour, to work out the longitude of point X from the difference. In other words, if the clock on board showed that it was, let us say, noon in Paris, and that in place X it was six in the afternoon, by translating every hour of difference into 15 degrees, we would have known that the longitude of place X was 90 degrees from the Paris meridian.

  Although it was not difficult to work out the time at the place where the calculation was being made, it was practically impossible to keep a mechanical clock on board that would function perfectly after months of sailing and the inevitable jolts, through winds and waves; hourglasses and water clocks were, of course, out of the question since they need to work on a flat motionless surface. And any clock would have to be of an extremely high precision: an error of four seconds would produce an error of one degree of longitude.

  One suggestion mentioned in various chronicles of the time was the use of Powder of Sympathy.

  This was a miraculous compound that, when applied to the weapon that had caused a wound, acted (through a sort of almost atomic continuity) on the particles of blood released into the air over the wound, even if the weapon and the injury were a great distance apart. This would heal the wound, allowing time to take its course, but as an immediate reaction it would cause irritation and pain.
