Quintus Poppaeus Q. f. Q. n. Secundus was consul suffectus in AD 9, and one of the authors of the lex Papia Poppaea.
[1][2][3] Secundus was appointed consul suffectus ex Kalendis Juliis[i] together with Marcus Papius Mutilus, succeeding Gaius Poppaeus Sabinus and Quintus Sulpicius Camerinus.
During their term of office, Papius and Poppaeus authored the law that bore their names.
[5][3] The lex Papia Poppaea was intended to discourage adultery, prevent the intermarriage of members of the senatorial class with freedmen or the children of freedmen, and encouraged lawful marriage and procreation, by establishing a set of regulations and legal penalties for those who remained unmarried or failed to produce children without receiving some sort of legal dispensation.
[6] Tacitus relates that the law failed to achieve its aims, and some eight years after its passage, the emperor Tiberius established a commission to ameliorate its penalties, due to the number of persons subjected to prosecution, the number of informers whom the law encouraged, and the vast amount of property confiscated under its provisions.
