The commentary of Proclus on the Timaeus is a wonderful monument of the silliness and prolixity of the Alexandrian Age. It extends to about thirty pages of the book, and is thirty times the length of the original. It is surprising that this voluminous work should have found a translator (Thomas Taylor, a kindred spirit, who was himself a Neo-Platonist, after the fashion, not of the fifth or sixteenth, but of the nineteenth century A.D.). The commentary is of little or no value, either in a philosophical or philological point of view. The writer is unable to explain particular passages in any precise manner, and he is equally incapable of grasping the whole. He does not take words in their simple meaning or sentences in their natural connexion. He is thinking, not of the context in Plato, but of the contemporary Pythagorean philosophers and their wordy strife. He finds nothing in the text which he does not bring to it. He is full of Porphyry, Iamblichus and Plotinus, of misapplied logic, of misunderstood grammar, and of the Orphic theology. Although such a work can contribute little or nothing to the understanding of Plato, it throws an interesting light on the Alexandrian times; it realizes how a philosophy made up of words only may create a deep and widespread enthusiasm, how the forms of logic and rhetoric may usurp the place of reason and truth, how all philosophies grow faded and discoloured, and are patched and made up again like worn-out garments, and retain only a second-hand existence. He who would study this degeneracy of philosophy and of the Greek mind in the original cannot do better than devote a few of his days and nights to the commentary of Proclus on the Timaeus. A very different account must be given of the short work entitled ‘Timaeus Locrus,’ which is a brief but clear analysis of the Timaeus of Plato, omitting the introduction or dialogue and making a few small additions. It does not allude to the original from which it is taken; it is quite free from mysticism and Neo-Platonism. In length it does not exceed a fifth part of the Timaeus. It is written in the Doric dialect, and contains several words which do not occur in classical Greek. No other indication of its date, except this uncertain one of language, appears in it. In several places the writer has simplified the language of Plato, in a few others he has embellished and exaggerated it. He generally preserves the thought of the original, but does not copy the words. On the whole this little tract faithfully reflects the meaning and spirit of the Timaeus.
