Gellius est tenuis: quid ni? cui tam bona mater
tamque valens vivat tamque venusta soror
tamque bonus patruus tamque omnia plena puellis
cognatis, quare is desinat esse macer?
qui ut nihil attingat, nisi quod fas tangere non est,
quantumuis quare sit macer invenies.

Gellius is lean: why shouldn't he be? Why would he who has such a good mother,
who lives so healthfully, who has such a lovely sister,
such a good uncle and such an abundance of consanguineous girls
stop being so scrawny?
You'll find the reason is that he remains scrawny in order that he might touch nothing
save as much as he wants of what he has no right at all to touch.
