"[The present edition] will long remain not only the standard commentary on this work, but an indispensable aid to every student of Cicero. Nisbet's choice of the neglected In Pisonem was a happy one. The speech--'a masterpiece of misrepresentation,' as the editor aptly describes it--is a lively and characteristic example of Cicero's mature oratorical style; it is full of historical interest, and the condition of the text still offers scope to a judicious editor.... If Nisbet's treatment of textual matters deserves the highest praise, scarcely less admirable is the lucid conciseness of his explanatory notes, which, especially on historical topics, are often models of their kind."--Journal of Roman Studies.
