Topography of ancient Rome

Ancient Roman topography as a systematic field of study began with the Italian Renaissance. The humanists express both a sense of rupture from the classical past brought about by the "Dark Ages" and a desire to rediscover antiquity. The renewed interest in classical texts, facilitated by the new technology of the printing press, was paralleled by inquiry into the physical monuments of ancient Rome, coinciding with a contemporary building boom in the city.[4]

Among the early topographers of ancient Rome were the 15th-century humanists Poggio Bracciolini and Flavio Biondo. Poggio's De varietate fortunae ("On the Vagaries of Fortune") was a nostalgic and moralizing evocation of a lost Rome of triumphs, spectacles, and grand monuments, but it also contained detailed descriptions of temples, baths, arches, amphitheaters and other landmarks as artifacts subject to intellectual inquiry, in contrast to medieval mirabilia literature.[5] Poggio researched ancient texts such as Frontinus's work On the Water Supply of the City of Rome and examined inscriptions, compiling a volume of epigraphy from ancient monuments: "Through such diligence, Poggio pioneered the way to reconstruct in historically accurate terms the topographical reality of the ancient city."[6]

Biondo, like Poggio an Apostolic Secretary, produced a series of volumes surveying the topography of the ancient city as well as Roman Italy: Roma instaurata (1440–46), Italia illustrata (1448–53), and Roma triumphans (1456–60). In these works, Biondo took an antiquarian or archaeological approach, as distinguished from his historical writing in the Decades which influenced Gibbon.[7]

He organized his material by topic, and not only described and identified gates, obelisks, baths, circuses, and other monuments, but explained their function and purpose. Among his literary and documentary sources were Livy's history of Rome, the letters of Pliny, Varro's De lingua latina, Festus, the regionary catalogues, and the newly discovered manuscripts of Tacitus and Frontinus.[8]

Although Renaissance researchers did not engage in archaeological digs, the archaeological and topographical perspective was fundamental to humanism, and they were alert to finds of antiquities. Biondo, for instance, was able to locate the atrium of the Theater of Pompey after a Roman lawyer who was having his wine cellar enlarged found a massive block of dressed stone inscribed with cubit-high letters reading Genius theatri Pompeiani.[9]

Biondo's methodology and use of textual sources influenced the archaeological, antiquarian, and topographical study of ancient Rome among his fellow humanists for the next 80 years. Among these were Pomponius Leto, who edited the Notitia regionum Urbis based in part on his experience as a tour guide; Bernardo Rucellai, with his compilation De Urbe Roma; and Andrea Fulvio, who published his massive Antiquitates Urbis in the spring of 1527, just before the sack.[10] The successor to Biondo's work was the seven-volume Antiquae Romae topographia of Bartolomeo Marliani, first published in May 1534,[11] but riddled with typographical errors. Bartolomeo credited the collaboration of various scholars, singling out Annibale Caro. The work was republished in a corrected, augmented second edition in 1544, as Urbis Romae topographia and rededicated, this time to Francis I of France. It was this second edition that was often reprinted, complete and in epitomes, and translated into the modern languages of Europe. But the first edition was the basis for an edition published the same year at Lyon, that was thoroughly revised and augmented by François Rabelais and dedicated to Jean du Bellay, with whom Rabelais had been staying in Rome in March through April 1534, just before Marliani's Topographia appeared; it would appear that Rabelais had contact with Marliani.[12]
