Philo Judaeus Legatio Ad Gaium 58

[58] He said Macro thought thus: "Caius is my work; the work of Macro. I am more truly, or at all events not less truly, his father than his own parents. He would have been destroyed, over and over again, by Tiberius, who thirsted for his blood, if it had not been for me and for my powers of persuasion. And moreover, when Tiberius was dead, I, who had under my command the whole force of the army, immediately placed him in the position which Tiberius had occupied, teaching him that the state had indeed sustained a loss of one man, but that the imperial authority continued unaltered, as entire as ever."
