Describes the collection of Horatiana in Groningen University Library, donated to the Library in 1871 and gradually enlarged since then. With over 1300 volumes this Horace collection is one of the largest in the world.

The present catalogue seeks to provide a comprehensive record of the 1,532 editions printed in the 15th and 16th centuries held in the legal historical section of the Biblioteca di Scienze Sociali of the Università degli Studi di Firenze. This library is the successor to that of the Facoltà di Giurisprudenza, the nucleus of which remains the historic collection of the Collegio degli Avvocati di Firenze acquired in 1924. Supplemented by further important acquisitions, including the library of the Corte di Appello di Firenze, the collection has come to be numbered among the foremost in its fi eld in Italy. It exhibits a wide range not only of the famous medieval authors of the ius commune, but also of the growing number of contemporary 16th century jurists.

The Swiss physician and polymath Conrad Gessner (1516-1565) was one of the most prominent scientists of the early modern period and wrote numerous important works. During the last two decades were discovered nearly 400 titles from his private library. They give an interesting insight into his interests and his sources. The present book contains not only an introduction and a catalogue of these books, but also inventories of the lost works as well as the still extant and lost manuscripts possessed by Gessner. They open the door to Gessner's study and to the intellectual world of a fascinating Renaissance scholar.
