There can be but little doubt that this is the work, and St. Ambrose the author, bitterly attacked by St. Jerome; the whole passage may be read in the Apology of Rufinus, p. 470, in vol. iii. of this series. St. Ambrose is compared to a daw decked in another bird’s plumage, and charged with writing “bad things in Latin taken from good things in Greek,” and St. Jerome even took the trouble to translate a work of St. Didymus on the Holy Spirit (from the preface to which the above extracts are taken), in order that those who did not know Greek might, St. Jerome hoped, recognize the plagiarisms.
