Because of the search engine in Literary Resource Center, I've added a link to the search results for Martial. Be sure to look at references to his contemporaries, or epigrams in general. The "Topic Finder" is fun.
This is a key source in Classical Studies scholarship. It provides basic background information on every aspect of classical life. The entries are written by experts on the particular topic, and end with additional references.
Encyclopedias from the Duke University Library Catalog
Oxford University Press created this encyclopedia of peer-reviewed annotated bibliographies in classical studies. In addition to the entry on Martial, linked below, use the encyclopedia to find other aspects of Rome in the Flavian period.
