O tempora, o mores![372]
Obscurus fio[404]
Obstinata mente perfer, obdura![408]
Obstupui, steterantque comae, et vox faucibus haesit[388]
Occidit miseros crambe repetita magistros[424]
Occupata in otio[401]
Oculus domini fertilissimus in agro[356]
Oderint dum metuant[371]
Odi profanum vulgus et arceo[394]
