"The verse is in Juvenal"

Decimus Iunius Iuvenalis, known in English as Juvenal, was a Roman poet of the late 1st and early 2nd century AD.  He authored the Satires, a collection of at least 16 poems covering a diverse range of topics.  The works are hyperbolic and comedic, and provide a wide-ranging discussion of society and social mores.  Juvenal describes the work as follows:

Back from when Deucalion climbed a mountain in a boat

as the clouds lifted the waters, and then asked for an oracle,

and then little by little spirit warmed the soft stones

and Pyrrha showed naked girls to their husbands,

whatever men do – prayer, fear, rage, pleasure

joy, running about – is the grist of my little book.
