Note 090
The edict itself, which is still extant among the epistles of Julian (xlii. [p. 422]), may be compared with the loose invectives of Gregory (Orat. iii. p. 96). Tillemont (Mem. Eccles. tom. vii. p. 1291-1294) has collected the seeming differences of ancients and moderns. They may be easily reconciled. The Christians were directly forbid to teach, they were indirectly forbid to learn, since they would not frequent the schools of the Pagans.
