Note 094
The chronology of Procopius is loose and obscure;
but with the aid of Pagi I can discern that John was appointed
Praetorian praefect of the East in the year 530 - that he was
removed in January, 532 - restored before June, 533 - banished in
541 - and recalled between June, 548, and April 1, 549. Aleman.
(p. 96, 97) gives the list of his ten successors - a rapid series
in a part of a single reign.
