This dictionary pretends to be an elemental prosopography of the ancient history of Greece and Rome. It collects, elaborated in synthetic form, the biography of the main personages who had a prominent participation in the historical events of the so-called classic civilizations. The work is conceived as a first contact with the protagonists of History, without implying lack of rigor or concern for an update of the data. The book includes as complement genealogical charts and lists of emperors, kings and magistrates that facilitate their use.
