Cassius Dio Cocceianus, Dio's Rome, Volume 4
“ I may of course meet with some catastrophe, as happens to many; for it is not possible for a man to please everybody, especially when he has been involved in so great wars, some foreign and some civil, and has had affairs of such magnitude entrusted to him: yet even so, I am quite ready to choose to die as a private citizen before my appointed time rather than to become immortal as a sole ruler. That very circumstance will bring me fame,—that I not only murdered no one in order to hold possession of the sovereignty but even died untimely in order to avoid becoming monarch. ”
