Flavius Monaxius (Greek: Μονάξιος;floruit 408–420) was a politician of theEastern Roman Empire,praefectus urbi ofConstantinople,Consul and twicepraetorian prefect of the East.
From 17 January 408 to 26 April 409 he waspraefectus urbi ofConstantinople. Towards the end of his term, there was a shortage of food in the city, caused by delay in the shipment of grain fromAlexandria to the capital, and the population revolted. The rebels burned thepraetorium and dragged Monaxius' carriage around the streets.[1] Grain supplies directed to other cities were sent to Constantinople, and the overall grain supply for the capital was re-organised. Monaxius also created an emergency fund, partially formed by senatorial contribution, to buy grain in case of shortage.[2]
He waspraetorian prefect of the East between 10 May and 30 November 414[3] and then a second time between 26 August 416 and 27 May 420; during his second tenure, he dedicated a church inPerinthus. Also, on October 5, 416, he issued an edict that removed the authority ofCyril of Alexandria over theparabolani.[4] In 419 he held the consulship; after this year, four of his servants became monks at the monastery of Saint Hypatius against his will.
