Vie d'Auguste, 39:

XXXIX. impetratisque a senatu decem adiutoribus unum quemque equitum rationem uitae reddere coegit atque in exprobratis alios poena, alios ignominia notauit, plures admonitione, sed uaria. lenissimum genus admonitionis fuit traditio coram pugillarium, quos taciti et ibidem statim legerent; notauitque aliquos, quod pecunias leuioribus usuris mutuati grauiore faenore collocassent.

Traduction Alexander Thomson[1]:

XXXIX. With the assistance of ten senators, he obliged each of the Roman knights to give an account of his life: in regard to those who fell under his displeasure, some were punished; others had a mark of infamy set against their names. The most part he only reprimanded, but not in the same terms. The mildest mode of reproof was by delivering them tablets, the contents of which, confined to themselves, they were to read on the spot. Some he disgraced for borrowing money at low interest, and letting it out again upon usurious profit.
