Guillaume Postel (25 March 1510 – 6 September 1581) was a Frenchlinguist,Orientalist, astronomer,Christian Kabbalist, diplomat,polyglot, professor,religious universalist, and writer.
Born in the village ofBarenton inNormandy, Postel made his way toParis to further his education. While studying at theCollège Sainte-Barbe, he became acquainted withIgnatius of Loyola and many of the men who would become the founders of theSociety of Jesus, retaining a lifelong affiliation with them. He enteredRome in the novitiate of the Jesuits in March 1544, but left on December 9, 1545 before making religious vows.
Postel was adept atArabic,Hebrew, andSyriac and otherSemitic languages, as well as the Classical languages ofAncient Greek andLatin, and soon came to the attention of theFrench court.[citation needed]

In 1536, whenFrancis I sought aFranco-Ottoman alliance with theOttoman Turks, he sent Postel as the official interpreter of the French embassy ofJean de La Forêt to theOttoman sultanSuleiman the Magnificent inConstantinople. Postel was also apparently assigned to gather interesting Eastern manuscripts for the royal library, today housed in the collection of oriental manuscripts at theBibliothèque Nationale in Paris.


InLinguarum Duodecim Characteribus Differentium Alphabetum Introductio ("An Introduction to the Alphabetic Characters of Twelve Different Languages"), published in 1538, Postel became the first scholar to recognize the inscriptions onJudean coins from the period of theFirst Jewish–Roman War as Hebrew written in the ancient "Samaritan" characters.[1]
In 1543, Postel published a criticism of Protestantism, and highlighted parallels betweenIslam and Protestantism inAlcorani seu legis Mahometi et Evangelistarum concordiae liber ("The book of concord between the Coran and the Evangelicals").[2]
In 1544, inDe orbis terrae concordia ("Concerning the Harmony of the Earth"), Postel advocated auniversalistworld religion. The thesis of the book was that allJews,Muslims,Hindus,Buddhists andPagans could beconverted toChristianity once all of the religions of the world were shown to have common foundations and that the Christian religion best represented these foundations. He believed these foundations to be the love of God, the praising of God, the love of mankind, and the helping of mankind.
In hisDe la République des Turcs ("Of the Turkish Republic"), Postel makes a rather positive description of theOttoman society.[3] His 1553Des merveilles du monde et principalemẽt des admirables choses des Indes & du nouveau monde is one of the earliest European descriptions ofreligion in Japan. He interprets Japanese religion in terms of his universalist views on religion, claiming that the indigenous Japanese religion was a form of Christianity and that one could still find evidence of their worship ofcrucifixes.[4] Such claims about Japanese religion were common in Europe at the time; Postel's writings may have influencedFrancis Xavier's expectations of Japan as he traveled there.[4]
Postel was also a relentless advocate of the unification of allChristian churches, a common concern during the period of theProtestant Reformation, and remarkably tolerant of other faiths during a time when such tolerance was unusual. This tendency led him to work with the Jesuits in Rome and thenVenice, but the incompatibility of their doctrine with his beliefs prevented his full membership in their order. Riccioli provides an alternative account in his biography of Postel inAlmagestum Novum - that Postel was ejected by St. Ignatius from the Jesuits after taking his vows.

Postel took an interest in geography in his course of lectures at the Collège Royal, now known asCollège de France, in 1537. He is believed to have spent the years from 1548 to 1551 traveling to theHoly Land andOttoman Syria, to collect manuscripts. After this trip, he earned the appointment of Professor of Mathematics and Oriental Languages at the Collège Royal. In 1552, he published a short compendium under the name,De Universitate Liber, perhaps inspired by that ofHenricus Glareanus (1527). This geographer had drawn two polar projections which remained in manuscript. Postel expanded uponDe Universitate Liber, which was published as theCosmographicae Disciplinae Compendium byJohannes Oporinus inBasel, in 1561.
InCosmographicae, Postel clearly set out his ideas on the continents of Asia (Semia, afterShem), Africa (Chamia orChamesia, afterHam), Europe (Iapetia, afterJapheth), the Americas (Atlantides), and Australia (Chasdia, afterCush).[6] He denoted the Americas asboreal andaustral, and distinctly separated them from Australia (Terre Australle orChasdia) by theStrait of Magellan (Fretum Martini Bohemi).Chasdia was a term created by Postel.
Cosmographicae has an index of 600 names, which Postel included in his 1578 world map,Polo aptata Nova Charta Universi. Australia is calledChasdia in three places: under the Americas (CHASDIAE residuum Atlantidis meridiana pars); under the Moluccas (CHASDIAE pars) where it is joined to an unnamed New Guinea with its Rio Saint Augustin; and under Africa (CHASDIAE pars adhuc incognita).
To the south of South America, he included the followinglegend:
Ce quart de globe, ou demy Hémisphere contient dedans sa longitude clxxx degrès [180º], partie Australle de l'Atlantide dicte Peru ou America par Americ Vespuce Florentin son inventeur, et davantage une partie de la Chasdia ou terre Australle vers les Isles Mologa ou Moluques. (This quarter of the globe, or half hemisphere, contains within its 180 degrees of longitude the southern part of the Atlantide called Peru or America byFlorentineAmerigo Vespucci its discoverer, and as well a part of Chasdia or Terra Australis toward the Mologa or Moluccas Islands.)[7][8]
The South Pole is alluded to:
Chasdia qui est vers le Gond ou Pole Austral ainsi appellée à cause que de la Meridionale partie ou Australe procede la Misericorde dicte Chassed (Chasdia which is toward the Hinge or South Pole, so called because from the southern or austral part originates Mercy called Chessed).[9]
Another legend on the same map over the southern continent reads:CHASDIA seu Australis terra, quam Vulgus nautarum di fuego vocant alii Papagallorum dicunt (Chasdia or Terra Australis, which the common sailors call Tierra del Fuego and others say is the Land of the Parrots).[5]
Postel’s world map strongly influencedGerard de Jode and others of the Antwerp school.[10]

After several years, Postel resigned his professorship and traveled throughoutCentral Europe, including theHabsburg Empire andRenaissance Italy. He returned to France after each trip, often by way of Venice. Through his efforts at manuscript collection, translation, and publishing, he brought many Ancient Greek, Hebrew, and Arabic texts into European intellectual discourse in the LateRenaissance andearly modern periods. Among these texts are:
To Postel, the human soul is composed of intellect and emotion, which he envisaged as male and female, head and heart. The soul'striadicunity is through the union of these two halves. Yet Postel did not mean a secondincarnation of divinity: his sentiment and language make it clear that he spokefiguratively.[12]

While working on his translations of theZohar and theBahir in Venice in 1547, Postel became the confessor of Mother Zuana, an elderly woman who was responsible for the kitchen of the hospital of San Giovanni e Paolo. Zuana confessed to experiencing divine visions, which inspired Postel to believe that she was a prophet, that he was her spiritual son, and that he was destined to be the unifier of the world's religions. When he returned from his second journey to the East, he dedicated two works to her memory:Les Très Merveilleuses Victoire des Femmes du Nouveau Monde andLa Vergine Venetiana.
Based on his own visions, these works brought Postel into conflict with theInquisition. Postel's ties, however, with the very men tasked with trying him led to a verdict ofinsanity, rather thanheresy, which could lead to the death penalty, and consequently Postel was confined to thepapal prisons in Rome.[13] He was released when the prison was opened upon the death ofPaul IV in 1559.CzechRenaissance humanist Šimon Proxenus ze Sudetu (1532–1575),[14] reports that in 1564 Postel was detained to the monastery ofSt. Martin des Champs in Paris, "because of his delusions on the Mother Jeanne".[15]
Postel resumed his life in Paris, but the allegedmiracle at Laon in 1566 had a profound effect on him, and that year he published an account of it,De summopere considerando miraculo, in which he again expounded upon the interrelatedness of all parts of the universe and his imminent restoration of the world order.[16] As a result, he was sentenced to house arrest by theParlement of Paris, and eventually spent the last eleven years of his life confined to the monastery of St. Martin des Champs. He died in Paris in 1581.
