If anything does happen to me, I shall fall with a contented and prepared mind; and, indeed, death cannot be disgraceful to a brave man, nor premature to one of consular rank, nor miserable to a wise man.

[Si quid obtigerit, aequo animo paratoque moriar. nam neque turpis1mors forti viro potest accidere neque immatura consulari nec misera sapienti.]

Marcus Tullius Cicero (106-43 BC) Roman orator, statesman, philosopher

Orationes in Catilinam [Catilinarian Orations], No. 4, § 2, cl. 3 (4.2.3) (63-12-05 BC) [tr. Yonge (1856), 4.3]

(Source (Latin)). Alternate translations:

if any thing should fall out amiss, I shall be contented and ready to die: For Death can never come dishonourable to a Valiant Person, nor untimely to him that is Consular, nor unfortunate to a Wise man.
[tr. Wase (1671), 4.3]

If I am doomed to fall a sacrifice in your cause, I am resigned to my fate. To a well-prepared spirit death can never be dishonourable; to a consul never premature; to a wise man it never can be an evil.
[tr. Sydney (1795)]

If anything shall happen to me, I shall die with a mind contented and prepared. For neither can a disgraceful death happen to a brave man, nor an untimely one to a man of consular rank, nor a wretched one to a wise man.
[tr. Mongan (1879), 4.2]

If any (thing) shall have befallen, I shall die with an equal and prepared mind. For neither a base death is able to happen to a brave man, nor an immature (death) to a consular (man), nor a wretched (death) to a wise man.
[tr. Underwood (1885), 4.2]

If any (thing) shall have befallen, I shall die with an equal [a calm] and prepared mind. For neither a base death is able to happen to a brave man, nor an immature (one) to a consular (man), nor a wretched (one) to a wise (man).
[tr. Dewey (1916), 4.2]

Death cannot be dishonorable to the brave man, or premature to him who has held high office, or lamentable to the philosopher.
