[Footnote 20: The honors of Belisarius are gladly
commemorated by his secretary, (Procop. Goth. l. iii. c. 35,
l. iv. c. 21.) This title is ill translated, at least in
this instance, by praefectus praetorio; and to a military
character, magister militum is more proper and applicable,
(Ducange, Gloss. Graec. p. 1458, 1459.)]
