This document provides an overview of the Greek historian Dionysius of Halicarnassus and his work "Roman Antiquities". It discusses his biography, intention in writing the work, methodology, and key sections including his account of Aeneas' wanderings and establishment of settlements in Italy which helped prove the Greek origins of the Romans. Dionysius synthesized information from over 50 sources to compose his own version of early Roman history from its founding to the First Punic War in order to make it accessible to a Greek audience and dispel myths about the Romans' barbarian origins.
