Here are presented all the ancient written references, both literary and epigraphical, to the Agora (including its environs) and its monuments. The introduction summarizes chronologically the authors cited, evaluating the contributions of each. The texts are given in the original Greek or Latin, followed by a translation and a commentary. They are grouped in parts: the Stoas, Shrines, Public Buildings and Offices, Market, Honorary Statues, Miscellaneous including Boundaries, Trees, Kerameikos, Panathenaic Street, Old Agora. Within each part the monuments are arranged alphabetically and under each monument the texts are listed alphabetically by author with inscriptions at the end. Many texts not given numbers in this order are included in the archaeological and topographical commentaries. Each section on a monument opens with a brief synopsis of the evidence contained in the texts which follow. The index of authors gives dates and editions as well as passages and inscriptions cited, and is followed by an index of subjects. The plates show plans of the Agora and its environs and of the route of Pausanias.
