Some few treatises, De Officiis, De excessu fratris Satyri, De Virginitate, and several other short ones, appear in German, in the select writings of the Fathers, published by Kosel of Kempten. The Epistles have been translated into French by Bonrecueil, Paris, a.d. 1746; and the De Officiis and Epistles into English, the former by Humfrey, London, a.d. 1637; the latter in the Oxford “Library of the Fathers,” revised by E. Walford, London, 1881; whilst the De Mysteriis appears in a little volume of Sacramental Treatises, published by Messrs. J. Parker & Co., Oxford, under the supervision of the Editor of this volume. There is a very valuable little monograph entitled Studia Ambrosiana, chiefly critical, and unfortunately brief, by Maximilian Ihm. Leipzig, Teubner, 1889.
