[1] After tutoring Nero, Anicetus was made commander of the fleet (praefectus classis) at Misenum[2] in 59 AD.
Nero wished to see his mother crushed in a collapsing boat, and employed Anicetus to see to it that this contraption was built.
Nero put this strategy into action, though the collapsing boat failed to kill Agrippina.
Afterwards, on 23 March AD 59, Anicetus himself stabbed Agrippina to death in her villa, on orders from Nero.
[4] For his supposed part in this crime, Anicetus was banished to Sardinia, where he lived in comfortable exile until his death of old age.
