Rudolf Hercher is especially known for his works on textual reconstruction. He mainly worked with Greek prose authors of the post-classical period, but also strayed into Homer, Herodotus and Latin authors. His first publication was a critical edition of the work On the Names of Rivers and Mountains (περὶ ποταμῶν καὶ ὀρῶν ἐπωνυμίας), in which he not only produced the text, but also established that the work's attribution to Plutarch was incorrect. He focussed on Arrian's On Hunting(De Venatione), Michael Psellos, Nikephoros Gregoras, the Dreambook of Achmet, Ptolemaios Chennos and Philo of Byzantium.
