In page Procopius:

"

It is not certain when Procopius died. Many historians—including Howard-Johnson, Cameron, and Geoffrey Greatrex—date his death to 554, but there was an urban prefect of Constantinople (praefectus urbi Constantinopolitanae) who was called Procopius in 562. In that year, Belisarius was implicated in a conspiracy and was brought before this urban prefect.[citation needed]
