In Episodes in the Life of the Early Modern Learned Book, Ian Maclean investigates intellectual life through the prism of the history of publishing, academic institutions, journals, and the German book fairs whose evolution is mapped over the long seventeenth century. After a study of the activities of Italian book merchants up to 1621, the passage into print, both locally and internationally, of English and Italian medicine and ‘new’ science comes under scrutiny. The fate of humanist publishing is next illustrated in the figure of the Dutch merchant Andreas Frisius (1630–1675). The work ends with an analysis of the two monuments of the last phase of legal humanism: the Thesauruses of Otto (1725–44) and Gerard Meerman (1751–80).
