cassius dio

lucius -lrb- or claudius -rrb- cassius dio -lrb- ; alleged to have the cognomen cocceianus ; `` dion kassios kokkeianos '' , c. ad 155 -- 235 -rrb- , known in english as cassius dio , dio cassius , or dio , was of greek origin , roman consul and noted historian who wrote in greek .
dio published a history of rome in 80 volumes , beginning with the legendary arrival of aeneas in italy ; the volumes then documented the subsequent founding of rome -lrb- 753 bc -rrb- , the formation of the republic -lrb- 509 bc -rrb- , and the creation of the empire -lrb- 31 bc -rrb- , up until ad 229 .
the entire period covered by dio 's work is approximately 1,400 years .
of the 80 books , written over 22 years , many survive into the modern age , intact , or as fragments , providing modern scholars with a detailed perspective on roman history .
