Julian was an able and a learned man. Gennadius speaks of him as "vir acer ingenio, in divinis Scripturis doctus, Graeca et Latina lingua scholasticus". He was of high character, and especially distinguished for generous benevolence, and seems actuated throughout the controversy by a firm conviction that he was acting in the interests of what he held to be the Christian faith and of morality itself. Besides his works already mentioned, Bede speaks of his Opuscula on the Canticles, and among them of a "libellus" de Amore, and a "libellus" de Bono Constantiae, both of which he charges with Pelagianism, giving from each some extracts. Garnier claims Julian as the translator of the "Libellus Fidei a Rufino Palaestinae Provinciae Presbytero", which he has published in his edition of Marius Mercator, and as the author of the liber "Definitionum seu Ratiocinationem", to which Augustine replied in his "de Perfectione Justitiae".
