Druso el Mayor
Crispinus Sulpicianus’ career is largely unknown; by 18 BC he was a "triumvir monetalis", and in 9 BC, he was elected consul, serving alongside Augustus' stepson Nero Claudius Drusus. During his consulship, he secured passage of the "lex Quinctia", which provided penalties for damage to aqueducts. It was also during his consulship that the "Ara Pacis" was inaugurated in the Campus Martius.
