Deliciæ Poetarum Germanorum, Collectore A. F. G. G. (Francofurti, 1612), Pars I. p. 685. / One of a series of mottoes for various Emperors, this being designed for Lothair I (795–855). / Among the epigrams of John Owen, the British Martial, we find (8, 58) a couplet, evidently inspired by the line of Borbonius: / Tempora mutantur, nos et mutamur in illis: / Quomodo? fit semper tempore pejor homo. / Times change, and we change with them too. How so? / With time men only the more vicious grow. / See also Tempora mutantur, and Alexander Pope, Moral Essays, Epistle I, line 172: / Manners with fortunes, humours turn with climes, / Tenets with books, and principles with times.
