Carlo Amoretti - Creator of Grand Geographical Illusion

Creator of Grand Geographical Illusion

Even while it is so poorly regarded Amoretti's work has left an enduring geographical puzzle—an invalid geographical assertion—which has only been recently detected.

In two footnotes on pages 66 and 72, Amoretti surmised that Magellan's port—which he named Massana and appears otherwise as Mazaua or Mazzaua in the clear calligraphic writing of the Beinecke-Yale codex, where the Armada de Molucca anchored from March 28 to April 4, 1521—may be the Limassava in a map of the Philippines by French cartographer Jacques N. Bellin.

Bellin's map is a perfect copy of a chart made by Fr. Pedro Murillo Velarde, S.J., of the Philippines in 1734. Murillo's map was such a brilliant and beautiful map many European mapmakers plagiarized it outright. To the credit of Bellin, he cites Murillo as his authority; he corrects Murillo's longitude which followed the erroneous entry of Pigafetta. The French Bellin was hydrographer to the king of France and one of the greatest and most important French cartographers of the mid-18th century. His works were of such excellence as to set a high standard and were widely copied throughout Europe. His map of the Philippines came out the same year that Murillo's map came out.

In any case, Amoretti offers one proof in support of his guess: the latitude of Limassava is at Pigafetta's latitude for Mazaua at 9°40' North. He was mistaken on two counts, Limasawa is at 9°56' North while Mazaua had three latitude readings by three members of the Armada, 9°40' N by Pigafetta, 9°20' N by Francisco Albo, and 9° N by the Genoese Pilot.

Mazaua was the port where Magellan's fleet anchored for one week. It was also the port where 22 years later, Ginés de Mafra, revisited, the only crewmember of the Armada to do so. There are other visits by Spanish and Portuguese during the entire Age of Sail, the last notable one a few months before the 1565 arrival of the Legazpi expedition being a Portuguese squadron that virtually wiped out the entire population of the isle except for one native who was able to hide.

Famous quotes containing the words creator, grand, geographical and/or illusion:

    The Creator has not thought proper to mark those in the forehead who are of stuff to make good generals. We are first, therefore, to seek them blindfold, and then let them learn the trade at the expense of great losses.
    Thomas Jefferson (1743–1826)

    The allurement that women hold out to men is precisely the allurement that Cape Hatteras holds out to sailors: they are enormously dangerous and hence enormously fascinating. To the average man, doomed to some banal drudgery all his life long, they offer the only grand hazard that he ever encounters. Take them away, and his existence would be as flat and secure as that of a moo-cow.
    —H.L. (Henry Lewis)

    Men’s private self-worlds are rather like our geographical world’s seasons, storm, and sun, deserts, oases, mountains and abysses, the endless-seeming plateaus, darkness and light, and always the sowing and the reaping.
    Faith Baldwin (1893–1978)

    There can be no greater error than to expect, or calculate, upon real favors from nation to nation. It is an illusion which experience must cure, which a just pride ought to discard.
    George Washington (1732–1799)
