sacredos fuit Ecclesiae Romanae" (de Sacramentis, III. §§ 5, 6).
As a writer, St. Ambrose left a multitude of works behind him, which show competent learning, a familiar acquaintance with Plato, Cicero, Vergil, and other classics, and much intellectual liveliness and industry. Their want of originality did not hinder them from obtaining for their author, through their popular and practical qualities, a distinguished reputation as a sound and edifying teacher. He is often mentioned with respect by his contemporaries, St. Jerome and St. Augustine (see especially the latter, de Doctrina Christianâ, iv. 46, 48, 50). He came to be joined with them and Gregory the Great as one of the four Latin doctors of the church. His writings may be classified under three heads, as (1) Expository, (2) Doctrinal or Didactic, and (3) Occasional.
(1) The first class contains a long list of expositions, delivered first as sermons, of many books of Scripture. They begin with the Hexaemeron, or commentary on the Creation. Of this work St. Jerome says, "Nuper S. Ambrosius sic Hexaemeron illius [Origenus] compilavit, ut magis Hippolyti sententias Basiliique sequeretur" (Ep. 41). It is in a great part a literal translation from St. Basil. St. Augustine was interested by the method of interpretation in which Ambrose followed Basil, Origen, and Philo Judaeus, finding a spiritual or mystical meaning latent under the natural or historical. The Hexaemeron (6 books) is followed by de Paradiso, de Cain et Abel (2), de Noe et Arcâ, de Abraham (2), de Isaac et Animâ, de Bono Mortis, de Fugâ Saeculi, de Jacob et Beatâ Vitâ (2), de Joseph Patriarchâ, de Benedictionibus Patriarcharum, de Eliâ et Jejunio, de Nabuthe Jezraelitâ, de Tobiâ, de Interpellatione Job et David (4), Apologia Prophetae David, Apol. altera ib., Enarrationes in Psalmos (12), Expositio in Ps. cxviii., Expositio Evang. secundum Lucam (10).
(2) The second class contains de Officiis Ministrorum (3 books), de Virginibus (3), de Viduis, de Virginitate, Exhortatio Virginitatis, de Lapsu Virginis Consecratae, de Mysteriis, de Sacramentis (6), de Poenitentiâ (2), de Fide (5), de Spiritu Sancto (3), de Incarnationis Dominicae Sacramento. Of these the books de Officiis, addressed to the clergy (imitated from Cicero), and those de Fide, mentioned above, are the most important.
(3) The occasional writings, which are biographically the most valuable, are the discourses de Excessu Fratris sui Satyri (2), de Obitu Valentiniani Consolatio, de Obitu Theodosii Oratio, and the Epistles, ninety-one in number, with the Gesta Concilii Aquileiensis inserted amongst them.
Various ecclesiastical writings have been attributed to Ambrose, which critical examination has determined to be spurious. [ Ambrosiaster.] Most of these are given in the Benedictine edition; in that of Migne there is an additional appendix, containing some other compositions which have borne Ambrose's name, but are either manifestly spurious or have no sufficient title to be considered genuine. Some of his genuine works appear to have been lost, especially one, mentioned with high praise by St. Augustine (Ep. xxxi. 8), against those who alleged that our Lord had learnt from Plato.
Of the connexion of St. Ambrose with the liturgical arrangement which bears his name, we know nothing more than what has been quoted above from Paulinus. [See D. C. A., arts. Liturgies; Ambrosian Music.]
There are three principal editions of Ambrose's works—that of Erasmus, the Roman, and the Benedictine. Erasmus's ed. was pub. at Basle, by Froben, in 1527. He divided the works into four tomes, with the titles, (1) Ethica, (2) Polemica, (3) Orationes, Epistolae, et Conciones, (4) Explanationes Vet. et Novi Testamenti. The great Roman edition was the work of many years' labour, undertaken by the desire of popes Pius IV. and Pius V., and begun by a monk who afterwards became pope with the name of Sixtus V. It was pub. in 5 vols. at Rome, in the years 1580‒1‒2‒5. This edition superseded all others, until the publication of the excellent work of the Benedictines (du Frische and Le Nourry) at Paris, A.D. 1686 and 1690. A small revised ed. of the de Officiis and the Hexaemeron has been printed in the Bibliotheca Pat. Eccl. Latin. Selecta (Tauchnitz, Leipz.). Some of his works are reprinted in the Vienna Corpus Ser. Eccl. Lat.; and in the 10th vol. of the Nic. and Post-Nic. Fathers are English trans. of select works. An elaborate Life of St. Ambrose by Baronius, extracted from his Annales, is prefixed to the Roman edition; but improved upon by the more critical investigations of the Benedictine editors, who have laid the basis for all subsequent Lives. (Cf. Th. Forshaw, Ambrose, Bp. of Milan, 1884; a Life by the duc de Broglie in Les Saints, 1899 (Paris). A cheap popular Life by R. Thornton is pub. by S.P.C.K. in their Fathers for Eng. Readers.)
Ammon (or Amon), St., the founder of the celebrated settlement of coenobites and hermits on and near Mons Nitria (Ruf. de Mon. 30); he is often styled the "father of Egyptian monasticism." He was contemporary with St. Anthony, and filled the same place in Lower Egypt as Anthony in the Thebaid. Being left an orphan by his parents, wealthy people near Alexandria, he was forced by his uncle to marry. But on the wedding day he persuaded his bride to take a vow of celibacy, and for eighteen years they lived together as brother and sister: afterwards with her consent he withdrew to Nitria, and from that time only visited his wife twice a year (Pall. Hist. Laus. 8). A great multitude of zealous disciples soon gathered round him; so that Palladius not many years later found about five thousand monks, some living quite alone, some with one or more companions; while six hundred "advanced in holiness" (τελείοι) dwelt apart from the rest in more complete isolation (ib.). Several miracles are related of Ammon (Socr. Hist. iv. 23; Soz. Hist. i. 14; Niceph. Hist. viii. 41).
Ammonius, a disciple of Pambo, and one of the most celebrated of the monks of Nitria. Being of unusual stature, he and his brothers Dioscorus, Eusebius, and Euthymius were called the Tall Brothers (Soz. Hist. viii. 12). Ammonius himself was distinguished by the epithet παρωτής (Niceph. Hist. xi. 37), in
