Cultivate virtue; after death she lives,
And by his virtues only man survives.

In Notes and Queries (vol. vi. 79 and 245, and vol. x. 362), R. Pierpoint refers us to Mathias Borbonius, Dictum Tiberii—one of a series of mottoes for various emperors—in connexion with the motto of the Earls of Shannon (Boyle), where the words are given in reverse order: Vivit post funera virtus.—"Virtue survives death." / Cf. Euripides, Fragment 722: / Αρετή δὲ, κἄν θάνη τις, ουκ απόλλυται, / ζῇ δ᾿ οὐκέτ ὄντος σώματος κακοῖσι δὲ / ἅπαντα φροῦδα συνθανὀνθ᾽ ὑπὸ χθονός. / Virtue’s not killed at death. The body dies / But virtue lives; while all that bad men had / Dies with them, and is clean gone underground.
