 By Augustus' decree, festivals were held in Mogontiacum at Drusus' death day and probably also on his birthday.Drusus' mother Livia, much affected by the death of her second son, took the advice of the philosopher Areus to put up many statues and images of Drusus and speak often about him.The surviving Latin work "Consolatio ad Liviam" is framed as an Ovidian message of consolation to Livia on this occasion, though it is generally considered a literary exercise "composed between the death of Livia [29 CE] and that of Tiberius [37 CE]".
