Quintus Claudius, Volume I by Ernst Eckstein is about the adventures of Herodianus on the rocks of Capreae. Excerpt: "It was in Rome itself, in the sublime solemnity of the Colosseum, among the ruins of the palaces of the Caesars and crumbling pillars of the temples of the gods, that the first dreamy outlines rose before my fancy of the figures here offered to the reader's contemplation. Each visit added strength to the mysterious impulse, to conjure up from their tombs these shadows of a mighty past, and afterward, at home, where the throng of impressions sorted and grouped themselves at leisure, my impulse ripened to fulfillment."
