Note 025 Julian. Orat. i. [p. 9]. He seems to call her the mother of Crispus. She might assume that title by adoption. At least, she was not considered as his mortal enemy. Julian compares the fortune of Fausta with that of Parysatis, the Persian queen. A Roman would have more naturally recollected the second Agrippina:-

Et moi, qui sur le trone ai suivi mes ancetres:
Moi, fille, femme, soeur, et mere de vos maitres.
