In this collection of essays Roman historical and biographical texts are studied from a literary point of view. The main interest of the author, Daniël den Hengst, professor emeritus of Latin at the University of Amsterdam, concerns the development of Roman historiography, the ways in which Roman historians present their work and the intertextual relations between these works and other literary genres. Special attention is given to the Historia Augusta and Ammianus Marcellinus, but also authors from the classical period, such as Cicero, Livy and Suetonius and their ideas about historiography are discussed. The articles demonstrate that a detailed interpretation of these texts in the original language is indispensable to understanding the aims and methods of ancient historians and biographers.
