Basilios Bessarion

Basilios (or Basilius) Bessarion (Greek: Βασίλειος Βησσαρίων; 2 January 1403 – 18 November 1472), a Catholic cardinal bishop and the titular Latin Patriarch of Constantinople, was one of the illustrious Greek scholars who contributed to the great revival of letters in the 15th century. He was educated by Gemistus Pletho in Neoplatonic philosophy. Later, he became a cardinal, and was twice considered for the papacy.[1] He has been mistakenly known also as Johannes Bessarion or Giovanni Bessarione due to an erroneous interpretation of Gregory III Mammas.



Bessarion was born in Trebizond, the Black Sea port in northeastern Anatolia that was the heart of Pontic Greek culture and civilization during the Byzantine and Ottoman periods. The year of his birth has been given as 1389, 1395 or 1403.[2]

Bessarion's Neoplatonism

Bessarion was educated in Constantinople, then went in 1423 to Peloponnese to study Neoplatonism under Gemistus Pletho. Under Pletho, he "went through the liberal arts curriculum…, with a special emphasis on mathematics…including the study of astronomy and geography" that would have related "philosophy to physics…cosmology and astrology" and Pletho's “mathematics would include Pythagorean number-mysticism, Plato’s cosmological geometry and the Neoplatonic arithmetic which connected the material world with the world of Plato’s Forms. Possibly it also included astrology…"[3] Woodhouse also mentions that Bessarion "had a mystical streak…[and] was proficient in Neoplatonic vocabulary…mathematics…and Platonic theology".[3]

Bessarion's Neoplatonism stayed with him his whole life, even as a cardinal. He was very familiar with Neoplatonist terminology and used it in his letter to Pletho's two sons, Demitrios and Andronikos, on the death of his still-beloved teacher in 1452.[4] Perhaps the most remarkable thing about his life was that a Neoplatonist could have played such a significant role in the Roman Church for at least a brief time, though he was attacked for his views by more orthodox Catholic academics shortly after his death.

Bessarion's life as a monk and role in the Council of Ferrara

On becoming a tonsured monk, he adopted the name of an old Egyptian anchorite Bessarion, whose story he has related. In 1436 became abbot of a monastery in Constantinople and in 1437, he was made metropolitan of Nicaea by the Byzantine Emperor John VIII Palaeologus, whom he accompanied to Italy in order to bring about a reunion between the Eastern (Orthodox) and Western (Catholic) churches. The emperor hoped to use the possibility of re-uniting the churches to obtain help from Western Europe against the Ottoman Empire. Bessarion participated in the Byzantine delegation to the Council of Ferrara-Florence as the most eminent representative of unionists, although originally belonged to the party of anti-unionists. On 6 July 1439 he was the one who read the declaration of the Greek Association of Churches in the cathedral of Florence, in the presence of Pope Eugene IV and the Emperor John VIII Palaeologus.[2]

Some have impugned Bessarion's sincerity in adhering to the Union.[citation needed] It has been argued[by whom?] that he was pragmatic patriot and thought religious Union would be the only hope and refuge for the Byzantine Empire faced with the Ottoman advance. However, Gill upholds Bessarion's sincerity in being convinced to the truth of the Roman position in the matters discussed at the Council quoting from the bishop's own Oratio Dogmatica:

But if we had discerned error in the doctrine of the Latins or distortion in their faith, not even I would have counseled you to embrace union and agreement with them in that case, that for fear of bodily ills you should prefer the values of the present world to spiritual values, the freedom of the body to the betterment of the soul, but I myself would have undergone all that is worst and I would have exposed you to it before I would have urged you to union with them and have recommended such action.[5]

Upon his return to the East, he found himself bitterly resented for his attachment to the minority party that saw no difficulty in a reconciliation of the two churches. At the Council of Ferrara-Florence (1438–1445), Bessarion supported the Roman church and gained the favour of Pope Eugene IV, who invested him with the rank of cardinal at a consistory of 18 December 1439.

From that time, he resided permanently in Italy, doing much, by his patronage of learned men, by his collection of books and manuscripts, and by his own writings, to spread abroad the new learning. His palazzo in Rome was a virtual Academy for the studies of new humanistic learning, a center for learned Greeks and Greek refugees, whom he supported by commissioning transcripts of Greek manuscripts and translations into Latin that made Greek scholarship available to Western Europeans. He supported Regiomontanus in this fashion and defended Nicholas of Cusa. He is known in history as the original patron of the Greek exiles (scholars and diplomats) including Theodore Gaza, George of Trebizond, John Argyropoulos and many others.

He held in succession the archbishopric of Siponto and the suburbicarian sees of Sabina and Frascati. At the papal conclave of 1455 which elected the Aragonese candidate, Alfons de Borja, as Callixtus III, Cardinal Bessarion was an early candidate for his disinterest in the competition between Roman factions that pressed candidates of the Orsini and Colonna factions.[6] He was opposed for his Greek background by the French Cardinal Alain de Coëtivy. "It is probable that the cardinals were less afraid of his Greek training and temperament than they were of his known austerity and passion for reform", Francis A. Burkle-Young[who?] has observed.[citation needed]

For five years (1450–1455), he was legate at Bologna, and he was engaged on embassies to many foreign princes, among others to Louis XI of France in 1471. Other missions were to Germany to encourage Western princes to help their fellow Christians in the East. For these efforts, his fellow humanist Aeneas Silvius Piccolomini, then Pius II, gave him the purely ceremonial title of Latin Patriarch of Constantinople in 1463.

As primus Cardinalium (from April 1463) — the title Dean of the Sacred College of Cardinals was not yet in use — Cardinal Bessarion presided over the Papal conclave, 1464[7] and Papal conclave, 1471.[8]

Vexation at an insult offered him by Louis XI is said[by whom?] to have hastened his death, which took place on 19 November 1472 at Ravenna. He is buried in the basilica of Santi Apostoli, Rome.


Bessarion was one of the most learned scholars of his time. Besides his translations of Aristotle's Metaphysics and Xenophon's Memorabilia, his most important work is a treatise directed against George of Trebizond, a vehement Aristotelian who had written a polemic against Plato, which was entitled In Calumniatorem Platonis ("Against the Slanderer of Plato"). Bessarion, though a Platonist, was not so thoroughgoing in his admiration as Gemistus Pletho, and he strove instead to reconcile the two philosophies. His work, by opening up the relations of Platonism to the main questions of religion, contributed greatly to the extension of speculative thought in the department of theology.

It was thanks to him that the Bibliotheca (Pseudo-Apollodorus), an important compendium of Greek Mythology, has survived to the present.

His library, which contained a very extensive collection of Greek manuscripts, was presented by him in 1468 to the Senate of the Republic of Venice, and forms the nucleus of the famous library of St Mark's, the Biblioteca Marciana. It comprised 482 Greek and 264 Latin manuscripts.[9]

Most of Bessarion's works are in Migne, Patrologia Graeca, vol. 161.
