Argyros, Isaac

ARGYROS, ISAAC

Antipalamite, Greek monk, theologian, and astronomer; d. c. 1375. Although Argyros followed the inspiration of Theodore Metochites and Gregoras in pursuit of astronomy and mathematics, he also proved himself to be a theologian and powerful polemist. Argyros ranged himself with Nicephorus Gregoras against gregory palamas and Emperor John VI Cantacuzenus in the controversy over hesychasm. He seems to have accepted the theological method of barlaam of calabria in his principal treatise against Palamism, written probably after 1360. He is also credited with a monograph on the teaching of Barlaam against Theodore dexios and is probably the author of a tome published by the patriarch of Antioch (c. 1370). Two further opuscules against Palamism are also attributed to him.

Besides theological treatises, Argyros wrote numerous scientific tracts that are still in manuscript: Apparatus astrolabii (Vatican), De reducendis triangulis (Oxford), De reducendo calculo astronomicorum (Vienna), Methodus Geodesiae (Escorial), Methodus solarium et lunarium (Leyden), and Geometriae aliquot problemata (Paris). His chief scientific works concern the sun and the moon cycles and the 12 winds. It is probable that Argyros wrote a short commentary on the works of Ptolemy relating in particular to the defective chapter of the Harmonics, a work to which Nicephorus had also given attention.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates.
