Valerius Maximus, Memorable Words and Deeds 2.5.3
“The poisoning-court, once unknown to Roman customs and laws, was instituted after many Roman matrons had been implicated in the crime. After these women in question had poisoned their husbands in a secret plot, they were indicted based on the testimony of a single serving-girl. A number of one hundred and seventy were condemned to death by the court.”
Veneficii quaestio, et moribus et legibus Romanis ignota, complurium matronarum patefacto scelere orta est. quae, cum viros suos clandestinis insidiis veneno perimerent, unius ancillae indicio protractae, pars capitali iudicio damnatae centum et septuaginta numerum expleverunt.
