Note 108
I agree with Tillemont (Hist. des Empereurs, tom. v. p. 726), in suspecting the royal pedigree, which remained a secret till the promotion of Theodosius. Even after that event, the silence of Pacatus outweighs the venal evidence of Themistius, Victor, and Claudian, who connect the family of Theodosius with the blood of Trajan and Hadrian.
