Phrynichus’ Praeparatio sophistica ranks not last among the most importat works of ancient scholarly literature which we wish we could read in its original, full redaction. It was Phrynichus’ magnum opus, and the high status of this work was still acknowledged in Byzantine intellectual circles. This volume brings some new light to the Praeparatio sophistica and its history, focusing on three areas of interest: (1) its context of production and linguistic theorisation; (2) its stylistic theorisation and interpretative framework; (3) the direct and indirect transmission from antiquity, through Late Antiquity, and down to the Byzantine era. The volume will be of interest to Classicists working on the linguistic theories of Atticism and the literary practice of the Second Sophistic.
