Abstract
Juvenal opens his eighth Satire with the question stemmata quid faciunt?, supplies an answer in line 20, nobilitas sola est atque unica virtus, and devotes the rest of the poem to exhorting his addressee to virtuous activity, both by negative exempla drawn from the degenerate nobility and by positive exempla drawn from the plebs, novi homines and the like. In lines 39–70 he addresses one particularly self-important noble and attempts to deflate his bombastic pride: in 56–67 he adduces an extended illustration from the animal world, apparently such as was common in the schools of rhetoric
