This collection of source material in Greek and Latin--literary, inscriptional, and numismatic--covers a period on which there is no adequate continuous treatment by any ancient writer. The paperback edition reprints with corrections the text of the second edition (1960), which has proved invaluable to students working on the last century of the Roman Republic. There is also a section of Addenda, and new Appendices give a fuller and more up-to-date text of the "Piracy Law" and a text of the important "Tarentum Fragment."
