Gaius Suetonius Tranquillus, Divus Augustus  31  (ca. A.D. 98-117):


Proximum a dis immortalibus honorem memoriae ducum praestitit, qui imperium p.  R.  ex minimo maximum reddidissent.  Itaque et opera cuiusque manentibus titulis restituit et statuas omnium triumphali effigie in utraque fori sui porticu dedicavit, professus et edicto: commentum id se, ut ad illorum vitam velut ad exemplar et ipse, dum viveret, et insequentium aetatium principes exigerentur a civibus.  Pompei quoque statuam contra theatri eius regiam marmoreo Iano superpossuit translatum e curia, in qua C.  Caesar fuerat occisus. 

Next from the immortal Gods he exhibited honos for the sake of the memory of the leaders who had rendered the power of the Roman people from least to greatest.  Therefore he both restored the works of these leaders with their original inscriptions, and in each of the two porticos of his forum dedicated statues of all these men in triumphal garb, even declaring by edict: I have contrived this to lead the citizens to require me, while I live, and the rulers of later times as well, to attain the standard set by those worthies of old.  He also put the statue of Pompeius over the marble arch opposite the regia of his theater, having transferred it from the curia, in which Gaius Caesar had been killed.  (U. K. Vestal, trans.)
