The excavation of the earliest Roman port and fishery known establishes Cosa as the center for the flourishing commercial activities of the powerful Sestius family and extends the international trading picture of the Romans back to at least the early second century B.C. Originally published in 1987. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
