This paper takes a fresh look at the sources of Leo the Deacon and comments
on what has been written about them by other Byzantinists. It will also
study Leo the Deacon?s style of writing, which is certainly innovative,
since the History he authored stands apart from the historiographical works
that preceded it, as it seeks to meld the new historiography that had
emerged from the circle of Constantine VII Porphyrogennetos with the
classical tradition. And Leo blazes new trails by praising specific
individuals, the vast majority of them military men, around whose actions
and achievements - on the field of battle, in the main - his narrative near
exclusively revolves. The paper then goes on to indicate that one of the
most important texts that has been identified as a source of Leo?s History
is the Pophyrogennetos? vast collection conventionally labelled the Excerpta
Constantiniana; the Excerpta are then re-evaluated, particularly in terms of
their links to Leo, which turn out to be close, as a number of examples
illustrate.
