Graee. vol. v. p. 748, &c), h;u compiled a list of I about 250 authors quoted by him in those portions of his writings which we still possess. A great degree of critical and philosophical acumen was not to be expected in one so ardently attached to the enthusiastic and somewhat fanatical system of Plotinus. His attempt to prove the identity of the Platonic and Aristotelic systems would alone be sufficient to show this. Nevertheless, his acquaintance with the authors whom he quotes was manifestly far from superficial ; but his judgment in using the stores of learning which he possessed was but small. Cyril (Adv.JuL vi. init.) quotes a passage from his history of philosophers, from which it appears that his account of Socrates was a mere farrago of the most absurd and calumnious stories respecting that philosopher. Indeed, his object would seem to have Deen to magnify Pythagoras at the expense of every other philosopher. Though far less confused and unintelligible than Plotinus, his statements of his own metaphysical views are often far from comprehensible. (See especially his Upos ra vof]Tu d<pop/u.ai.) Of the very numerous writings of Porphyrius the following are extant: — 1. YlvOayopovfiios ; supposed by many to be a fragment of his larger history .of philosophers. 2. Ilep: HX^rivov j8:ou Kal ttjs Taboos tup $i@\.iwv o.vtov. [plotinus]. 3. Hepi dirox'ns t£v e/^o'xwz/, in four books, dedicated to his friend and fellow-disciple Firmus Castricius. 4. Fragments of his epistle IIpo.v 'Aveg&J tov AlyvTTTLov. Large quotations from this work are made by Eusebius in his Praeparatio Evangelica. 5. Upos ra vor\ra atpop/xcu. 6. '0,107-pitta fty-TT^uara, addressed to Anatolius. 7. Hepi tov lv 'OSudaefa to>j> Nvjj.<poov dvrpov, a fanciful allegorical interpretation of the description of the cave of the nymphs in the Odyssey, showing both the ingenuity and the recklessness with which Porphyrius and other writers of his stamp pressed writers and authorities of all kinds into their service, as holders of the doctrines of their school. 8. A fragment from a treatise Tlepl Srirycfc, preserved by Stobaeus. 9. Eto-ayuyf], or Hepl ru>v Trevre cf)wi>w)/, addressed to Chrysaorius, and written by Porphyrius while in Sicily. It is commonly prefixed to the Organon of Aristotle. 10. A Commentary on the Categories of Aristotle, in questions and answers. 11. Some fragments of a Commentary on Aristotle's books TLepl qvgikijs a/cpodVews. 12. A Commentary on the Harmonica of Ptole-maeus, leaving off at the seventh chapter of the second book. 1 3. Ilepl irpoo-q>$ias (see Villoison, Anecd. Graeca^ vol. ii. p. 103—118). 14. Scholia on the Iliad, preserved at Leyden, among the books and papers of Is. Vossius. A portion of them was published by Valckenaer, in an appendix to Ursi-nus's Virgil, with a copious account of the scholia generally. Other scholia on the Iliad, preserved in the Vatican library, were published by Villoison (Anecd. Or. ii. p. 266, &c.), and in his edition of the Iliad. 15. Portions of a Commentary, apparently on the Ethics of Aristotle, and of one on the Organon. 16. Two books on the philosophy of Plato were affirmed to be extant by Gesner. i 7. An epistle to his wife Marcella. This piece was discovered by Angelo Mai, in the Ambrosian library, and published at Milan, in 1816. The letter is not quite complete, as the end of the MS. is mutilated. The contents of it are of a general philosophical character, designed to incite to the practice
of virtue and self-restraint, and the study of philosophy. The sentiments are a little obscure here and there, but many of the maxims and remarks exhibit great wisdom, and a considerable depth of very pure religious feeling. He considers sorrow to be a more wholesome discipline for the mind than pleasures (c. 7). With great energy and some eloquence he urges the cultivation of the soul and the practice of virtue, in preference to attention to the body. His views of the Deity, of his operations, nd the right mode of contemplating and worshipping him, are of a very exalted kind, some reminding the reader strongly of passages in the Scriptures. The laws under which man is placed he distinguishes into natural, civil, and divine, and marks out their respective provinces- with considerable beauty and clearness. 18. A poetical fragment, from the tenth book of a work entitled Yltpl rfjs e/c \oyioov <ptAG<ro(/Has', is published at the end of the preceding work. 19. An introduction to the Tetrabiblos of Ptolemaeus is also attributed by some to Porph vrius, bv others to Antiochus. The
