R. B. Steele here discusses at length Livy's use of the gerund in his Ab Urbe Condita, a history of the Roman world from its foundation to the time of Augustus. Next to the ablative absolute, the gerunds and gerundives are the most commonly recurring construction in Livy, making his work an excellent place to evaluate the situations in which this construction occurs. The gerund is often a troubling feature of grammar to the intermediate student of Latin and continues to pose problems into advanced prose composition courses and the like. This article does a great deal to clarify the normal usage of this form of expression, and Steele's characteristically readable style makes the essay an interesting and rewarding read.
