This volume is part of the continuation of Felix Jacoby's monumental collection of fragmentary Greek historiography. It contains new editions of the Greek paradoxographers of the Imperial Period and of uncertain date, fragmentary and non-fragmentary alike. It also includes the fragments of the related types of works On rivers and On stones. For the first time, all these texts have been provided with a comprehensive commentary. Together with volume IV E 1, this will constitute a new corpus of Greek paradoxography which will make Greek thought on the marvelous accessible to scholars of antiquity and later times.
