As I think, I am becoming a god. Vespasian
Jam Tiberium vires et corpus, non dissimulatio, deserebant.
“His powers of body were gone, but his power of dissimulation still remained.” Tacitus
Dissimulation means concealing one’s thoughts or true character.
Livia, conjugii nostri memor, vive et vale
Livia, ever mindful of our union, live on, and fare thee well. Augustus Caesar (On his deathbed)
Cogita quamdiu eadem feceris; mori velle, non tantum fortis, aut miser, sed etiam fastidiosus potest.
Consider how long you have done the same things; a man may wish to die not only because he is brave, or unhappy, but also because he is simply tired of living. Seneca
