Imagines et elogia virorum illustrium et eruditor ex antiquis lapidibus et nomismatib expressa cum annnotationib ex bibliotheca Fulvi Ursini, issued in Rome in 1570 by librarian, collector, epigrapher and classical scholar Fulvio Orsini, was the first critically assembled collection and edition of ancient portraiture. An expert on ancient coins, gems, inscriptions, and statues, Orsini was most advantageously positioned to make the first critical collection of ancient portraiture. In the Imagines et elogia he combined portraits with brief biographies of subjects drawn from ancient history and literature. Unlike previous works such as Paolo Giovio's Vitae virorum illustrium (1549‑57) and Guillaume Rouillé's Promptuarium iconum insigniorum (1553), Orsini emphasized the original physical state of the portraits illustrated rather than modifying his reproductions of the portraits to fit them into a uniform format. He also illustrated the marbles and coins as objects, sometimes presenting one or more examples of each subject. A special feature of Orsini's work was the large number of headless herm (ἑρμῆς) portraits illustrated with inscriptions on their pedestals, making the work first a corpus of epigraphical testimonia to famous and not so famous Greeks and Romans, and secondly a repertory of portraits.
"Not only did Orsini have access to the most extensive epigraphical and iconographic collections in Rome but, more importantly, the critical method he employed in editing texts of classical authors and inscriptions served him well in the authentication of portraits. In making an identification, Orsini sought the evidence of an ancient inscription either directly on the marble or on a coin or medal that could be associated with a marble. He also collected ancient literary sources relating to the physical appearance or to the existence of ancient portraits of individual subjects. He did not hesitate to reject modern inscriptions whether on marble statuary or on gems, and he similarly rejected numismatic forgeries which by the late sixteenth century had flooded the Roman antiques market."
"In the majority of cases, Orsini (or his patron) owned the ancient coins, gems, busts, and statues that served his identifications. Hence, unlike virtually all of his predecessors, Orsini relied on 'autopsy' or first-hand experience as a critical method, anticipating the rigorous method of nine- teenth-century epigraphers like Theodor Mommsen. Orsini has been called the 'father of ancient iconography,' and, indeed, a glance at Gisela Richter's authoritative Portraits of the Greeks suffices to demonstrate the modern archaeologist's indebtedness to Orsini for the identification of a surprising number of heads of famous Greeks and Romans. Nevertheless, the documentary value of Orsini's earlier work is somewhat compromised by the fact that information about provenance is not presented consistently but, when offered, is usually buried near the end of the elogium" (Dwyer, "André Thevet and Fulvio Orsini: The Beginnings of the Modern Tradition of Classical Portrait Iconography in France," The Art Bulletin, 75, No. 3 (Sept. 1993), 467-480, quoting from 469).
