PSELLUS (Gr.'I' XXor)  , the name of several Byzantine writers, of whom the following may be mentioned: I . MICHAEL PSELLUS the elder, a native of Andros and a pupil of Photius, who flourished in the second half of the 9th century . His study of the Alexandrine theology, as well as of profane literature, brought him under the suspicions of the orthodox, and a former pupil of his, by name Constantine, accused him in an elegiac poem of having abandoned Christianity . In order to perfect his knowledge of Christian doctrine, Psellus had recourse to the instructions of Photius, and then replied to his adversary in a long iambic poem, in which he maintained his orthodoxy . None of his works has been preserved . 2 . MICHAEL CONSTANTINE PSELLUS the younger, born in Io18 (probably at Nicomedia; according to some, at Constantinople) of a consular and patrician family . He studied at Athens and Constantinople, where he became intimate with John Xiphilinus . Under Constantine Monomachus (1042-1054) he became one of the most influential men in the empire . As professor of philosophy at the newly founded academy of Constantinople he revived the cult of Plato at a time when Aristotle held the field; this, together with his admiration for the old pagan glories of Hellas, aroused suspicions as to his orthodoxy . At the height of his success as a teacher he was recalled to court, where he became state secretary and vestarch, with the honorary title of "Tlraroc r&av (Ist ocrh xav (prince of philosophers) . Following the example of his friend Xiphilinus he entered the monastery of Olympus (near Prusa in Bithynia), where he assumed the name of Michael .

But, finding the

life little to his taste, he resumed his public career . Under Isaac Comnenus and Constantine Ducas he exercised great influence, and was prime minister during the regency of Eudocia and the reign of his pupil Michael Parapinaces (1071-1078) . It is probable that he died soon after the fall of Parapinaces . Living during the most melancholy period of Byzantine history, Psellus exhibited the worst faults of his age . He was servile and unscrupulous, weak, fond of intrigue, intolerably vain and ambitious . But as a literary man his intellect was of the highest order . In the extent of his knowledge, in keenness of observation, in variety of style, in his literary output, he has been compared to Voltaire; but it is perhaps as the forerunner of the great Renaissance Platonists that he will be chiefly remembered . His works embraced politics, astronomy, medicine, music, theology, jurisprudence, physics, grammar and history . Of his works, which are very numerous, many have not yet been printed . We may mention: Chronographia (from 976-1077), which in spite of its bias in favour of the Ducases is a valuable history of his time, chiefly on domestic affairs; three Epitaphioi or funeral orations over the patriarchs Cerularius, Lichudes and Xiphilinus . His letters (nearly 500 in number) are also full of details of the period . A complete list of his works is given in Fabricius, Bibliotheca graeca, x .
