Building on Calvino's observations on Exactitude in Six Memos for the Next Millennium, the present book elucidates on the possible definitions of exactitude, the endeavor of reaching exactitude, and the undeniable limits to the achievement of this ambitious milestone. The eighteen essays in this interdisciplinary volume show how ancient and medieval authors have been dealing with the problem of exactitude vs. inexactitude and have been able to exploit the ambiguities related to these two concepts to various ends. The articles focus on rhetoric and historiography (section I), exact sciences and technical disciplines (II), the peculiarity of quotations (III), cases of programmatic inexactitude (IV) and textual transmission (V). Several interconnected questions weave a net across the volume: to what extent is exactitude the goal in ancient and medieval texts? How can the concepts of accuracy and inaccuracy aid the reinterpretation of an already known text or fact? To what extent can certain definitions of exactitude be stretched, without turning into inexactitude? The volume presents an extensive study capable of highlighting the shrewdness and aptness of the concepts introduced by Calvino more than thirty years ago.

This book offers the hint for a new reflection on ancient textual transmission and editorial practices in Antiquity.In the first section, it retraces the first steps of the process of ancient writing and editing. The reader will discover how the book is both a material object and a metaphorical personification, material or immaterial. The second section will focus on corpora of Greek texts, their formation, and their paratextual apparatus. Readers will explore various issues dealing with the mechanisms that are at the basis of the assembling of ancient Greek texts, but great attention will also be given to the role of ancient scholarly work. The third section shows how texts have two levels of authorship: the author of the text, and the scribe who copies the text. The scribe is not a medium, but plays a crucial role in changing the text. This section will focus on the protagonists of some interesting cases of textual transmission, but also on the books they manufactured or kept in the libraries, and on the words they engraved on stones. Therefore, the fresh voices of the contributors of this book, offer new perspectives on established research fields dealing with textual criticism.

Chance, in addition to the unavoidable ambiguity caused by time, is one of the main guilty parties in the transmission of ancient texts - or lack thereof. However, the same cannot be said for what concerns the mechanisms of selection and loss of historical and literary memory, where the voluntary awareness of obscuring is often part of a precise aim, thus leading the cultural memory of a literate society to become fragmented. The present volume explores the devices and criteria of selection and loss in Ancient and Medieval texts and the subsequent fragmentation of such literature, but it also addresses the questions of the damnatio memoriae, of literary strategies such as reticence and omission, as well as of known texts deemed lost but re-found thanks to state-of-the-art methods in digitization. The many and diverse nuances of the concepts of omission, selection, and loss throughout Ancient and Medieval literature and history are illustrated through a number of case studies in the four sections of this volume, each examining a different facet of the topic: 'Mechanisms and criteria of textual loss and selection', 'Lost texts re-discovered', 'Voluntary omissions and desire for oblivion', and 'Re-working the known'.
