   • Seneca the Elder, Suasoriae 6.1:

     M[ārcus] Catō, sōlus maximum vīvendī moriendīque exemplum, morī māluit quam rogāre (nec erat Antōnium rogātūrus), et illās usque ad ultimum diem pūrās ā cīvīlī sanguine manūs in pectus sacerrimum armavit.

     Marcus Cato, alone our noblest pattern in life and in death, chose to die rather than beg for mercy - yet it was no Antony he had to petition - and armed those hands of his, to the last unstained by Roman blood, against his own noble breast.
