Isaac Argyri opera omnia theologica necnon Iohannis ex-imperatoris Cantacuzeni Oratio adversus Argyrum

the long version

Isaac Argyros was a leading astronomer and theologian of the late 14th century, who spent most of his life at the Chora monastery in Constantinople. Besides several works on astronomy, he wrote a number of treatises against the Palamites in the tradition of his teacher and mentor Nicephorus Gregoras: (1.) De quattuor modis participationis Dei; (2.) De lumine Transfigurationis ad Gedeonem Zographum; and (3.) Solutio quaestionis cuiusdam Palamiticae. Former emperor John Cantacuzenus composed a lenghty treatise against Argyros (Contra Argyrum), in which he attacks the fact that Argyros and his followers deny three things: that the seven spirits referred to by Isaiah are uncreated; that the grace of God is uncreated; and that men receive gifts of God in an immediate manner." --
