"Authoritative ... highly readable". -- Bernard Knox, Atlantic Monthly

"An excellent study of the brief reign of Caligula....Barrett is a highly competent historian and clear writer, and the intrinsic interest of his subject is so great that the tougher kind of reader, as well as the scholar, will study this book with pleasure as well as with instruction". -- Hugh Lloyd-Jones, New York Review of Books

"Barrett's Caligula fills a long-standing void in providing a balanced, thoroughly documented, and persuasive assessment of Caligula's life and career. This eminently readable book's value is further enhanced by the illustrations and by an appendix discussing Caligula's statuary and coinage. It will prove a welcome addition to the library of anyone with interests in Roman history and culture". -- Joseph J. Hughes, Classical World

"I do not think that any scholar interested in the Julio-Claudian period or any classics or ancient history library could be without this book. Very well written, it should also be popular with the general public". -- Colin M. Wells
