Maclardy's volume is an irreplaceable primary resource for every reader of Cicero's First Oration Against Catiline. At the bottom of each page below the text, each Latin word is completely parsed and includes helpful references to the revised grammars of Allen and Greenough, Bennett, Gildersleeve, and Harkness. The Latin text is accompanied by an interlinear word-for-word translation. A more polished translation is found in the margin next to sections of the Latin text. Maclardy's commentary also delves into word derivations and word frequencies, thus making this volume helpful for the competent reader of Latin as well as the novice. A new introduction by Steven Cerutti of East Carolina University provides guidelines for the use of this resource by high school Latin teachers and educators at all levels.
