He has devoted him to study several matters about which he wrote
several books: the expansion from Tyrrhenian zone to middle and
high Adriatic and the age of overseas conquests. In particular he
has treated the second war between Rome and Carthago and the
character of Hannibal. About the imperial history he has devoted
him to study imperial structure's evolution until the period of

cooperates for the republican period to the encyclopedia of the
Roman army (ed. Blackwell)
