Ausonius was of Gallic blood by both parents; he was educated in grammar and rhetoric at the university of Bordeaux, and was afterwards for many years professor of both subjects at that of Trèves. As tutor to Gratian, son and successor of the Emperor Valentinian, he established himself in court favour, and fulfilled many high State offices. After Gratian was succeeded by Theodosius he retired to a lettered ease near his native town, where he lived till nearly the end of the century. His numerous poetical works are of the most miscellaneous kind, ranging from Christian hymns and elegies on deceased relations to translations from the Greek Anthology and centos from Virgil. Among them the volume of _Idyllia_ constitutes his chief claim to eminence, and gives him a high rank among the later Latin poets. The gem of this collection is the famous _Mosella,_ written at Trèves about the year 370. The most beautiful of purely descriptive Latin poems, it is unique in the felicity with which it unites Virgilian rhythm and diction with the new romantic sense of the beauties of nature. The feeling for the charm of landscape which we had occasion to note in the letters of the younger Pliny is here fully developed, with a keener eye and an enlarged power of expression. Pliny's description of the Clitumnus may be interestingly compared with the passage of this poem in which Ausonius recounts, with fine and observant touches, the beauties of his northern river--the liquid lapse of waters, the green wavering reflections, the belt of crisp sand by the water's edge and the long weeds swaying with the stream, the gleaming gravel-beds under the water with their patches of moss and the quick fishes darting hither and thither over them; or the oftener-quoted and not less beautiful lines where he breaks into rapture over the sunset colouring of stream and bank, and the glassy water where, at evening, all the hills waver and the vine-tendril shakes and the grape-bunches swell in the crystal mirror. In virtue of this poem Ausonius ranks not merely as the last, or all but the last, of Latin, but as the first of French poets. His feeling for the country of his birth has all the romantic patriotism which we are accustomed to associate with a much earlier or a much later age.
