Macro

Naevius Sutorius Macro (21 BCE-38 CE) succeeded Sejanus as Praefectus Praetorio of the Praetorian Guard in 31 CE.

Like his predecessor, he continued to conduct Treason Trials, ‘Maiestas’, against Senators and wealthy Equestrians until 34 CE.
He became friends with Caligula (37-41 CE) and allowed his wife Eunia to conduct an affair with Caligula.
He may have been ordered by Caligula to smother the aged Tiberias in 37 CE.
However his friendship soon turned sour when Caligula became Emperor.
In 38 CE, thinking he was being promoted as Prefect of Egypt, he and Eunia boarded a ship at Ostia only to be arrested and dismissed from Office. They then both committed suicide.
