One of the most erudite, as well as one of the most spiritual, of the _literati_ of any age or people, and certainly the most estimable of all the extant Greek philosophers after the days of Plutarch, was born either at Tyre or at some neighbouring town. His original name, Malchus, the Greek form of the Syrian Melech (king), and the name by which he is known to us, Porphyrius (purple-robed), we may well take deservedly to mark his philosophic superiority. He was exceptionally fortunate in his preceptors--Longinus, the most eloquent and elegant of the later Greek critics, under whom he studied at Athens; Origen, the most independent and learned of the Christian Fathers, from whom, probably, he derived his vast knowledge of theological literature; and, finally, Plotinus, the famous founder of New-Platonism, who had established his school at Rome in the year 244. Upon first joining the school of Plotinus, he had ventured to contest some of the characteristic doctrines of his new teacher, and he even wrote a book to refute them. Amerius, his fellow-disciple, was chosen to reply to this attack. After a second trial of strength by each antagonist, Amerius, by weight of argument induced Porphyry to confess his errors, and to read his recantation before the assembled Platonists. Porphyry ever after remained an attached and enthusiastic follower of the beloved master, with the final revision and edition of whose voluminous works he was entrusted. He had lived with him six years when, becoming so far unsettled in his mind as even to contemplate suicide in order to free himself from the shackles of the flesh, by the persuasion of his preceptor he made a voyage to Sicily for the restoration of his health and serenity of mind. This was in 270, in the thirty-seventh year of his age. Returning to the capital upon the death of his master, he continued the amiable but vain work of attempting the reform of the established religion, which had then sunk to its lowest degradation, and to this labour of love he may be said to have devoted his whole life. At an advanced age he married Marcella, the widow of one of his friends, who was a Christian and the mother of a rather numerous progeny, with the view, as he tells us, of superintending the education of her children. About sixty separate works of Porphyry are enumerated by Fabricius, published, unpublished, or lost; the last numbering some forty-three distinct productions. The most important of his writings are--
