41. The sixth book of Socrates, the eighth of Sozomen, and the fifth of Theodoret, afford curious and authentic materials for the Life of John Chrysostom. Besides those general historians, I have taken for my guides the four principal biographers of the saint:- 1. The author of a partial and passionate Vindication of the Archbishop of Constantinople, composed in the form of a dialogue, and under the name of his zealous partisan, Palladius, bishop of Helenopolis (Tillemont, Mem. Eccles. tom. xi. p. 500-533). It is inserted among the works of Chrysostom, tom. xiii. p. 1-90, edit. Montfaucon. 2. The moderate Erasmus (tom. iii. Epist. MCL. p. 1331-1347, edit. Lugd. Bat.). His vivacity and good sense were his own; his errors, in the uncultivated state of ecclesiastical antiquity, were almost inevitable. 3. The learned Tillemont (Mem. Ecclesiastiques, tom. xi. p. 1-405, 547-626, etc. etc.), who compiles the Lives of the saints with incredible patience and religious accuracy. He has minutely searched the voluminous works of Chrysostom himself. 4. Father Montfaucon who has perused those works with the curious diligence of an editor, discovered several new homilies, and again reviewed and composed the Life of Chrysostom (Opera Chrysostom. tom. xiii. p. 91-177).
