This volume takes a new look at one of the greatest works of Hellenistic mathematics, Apollonius of Perga’s Conica. It provides a long overdue alternative to H.G. Zeuthen’s Die Lehre von den Kegelschnitten im Altertum. The central part of the volume contains a historically sensitive analysis and interpretation of the entire Conica, both from the standpoint of its individual books and of the text as a whole.
