This course runs in two parallel strands. In the first we study the history of Greek philology from the beginnings to the present day. Important stopping points include the Museum of Alexandria; Byzantine philology from Eustathius to Triclinius; the Italian and French Renaissance; the genesis of Lachmann's method; Nietzsche vs Wilamowitz; Parry and the philology of oral texts; world philology; machine learning and the future of philology. In the second, practical, strand we work with the Princeton-based language model Logion to explore the benefits and limitations of computer-supported philology and tackle real-life philological problems.
