The notoriety of these festivals, where many kinds of crimes and political conspiracies were supposed to be planned, led in 186 BC to a decree of the Senate—the so-called Senatus consultum de Bacchanalibus, inscribed on a bronze tablet discovered in Calabria (1640), now at Vienna—by which the Bacchanalia were prohibited throughout all Italy except in certain special cases which must be approved specifically by the Senate.
A notoriedade destas festas, onde se supuña que se planeaban moitas clases de crimes e conspiracións políticas, provocou en 186 a.C. un decreto do Senado -o chamado Senatus consultum de Bacchanalibus, inscrito nunha taboíña de bronce descuberta en Calabria (1640) e actualmente en Viena- polo que as bacanais foron prohibidas en toda Italia, excepto en certas ocasións especiais que debían ser aprobadas especificamente polo Senado.
