[Augustus determined that the following activities should take place in his Forum:] Those passing from the class of boys to young men of military age should all be enrolled here; those appointed to commands abroad should set out from here; the Senate should make decisions here regarding the awarding of triumphs, and those celebrating a triumph should dedicate both crown and scepter to the War God here; for anyone awarded a triumph or other military honor, a statue in bronze should be set up in the forum; any military standards captured by an enemy and then recovered should be placed in the temple.
