Magnus Maximus
On 10 March 388, Christians deemed heretics were forbidden from residing in cities. On 14 March, Theodosius banned the intermarriage of Jews and Christians. In summer 388, Theodosius recovered Italy from Magnus Maximus for Valentinian, and in June, the meeting of Christians deemed heretics was banned by Valentinian. Around July, Magnus Maximus was defeated by Theodosius at Siscia (Sisak) and at Poetovio (Ptuj), and on 28 August, Magnus Maximus was executed by Theodosius. According to the "Consularia Constantinopolitana", Arbogast killed Flavius Victor (), Magnus Maximus's young son and co-"augustus", in Gaul in August/September that year. "Damnatio memoriae" was pronounced against them, and inscriptions naming them were erased.
