A remarkable blue-grey marble horse with a white marble rider, found in the Basilica at Aphrodisias, has been a focus of recent research. The article describes the archaeology and history of the monument—how it can be reconstructed, with its base and in its precise setting in the Basilica. The group was a daring composition that had already fallen and been restored once in antiquity. What emerges is firstly a new full-size hellenistic-style statue group whose subject can be identified as Troilos and Achilles, and secondly a striking example of the long second lives of classical statues in late antiquity. The horse was a great public monument of the early imperial period that was moved to the Basilica probably in the mid-fourth century AD, where it has a well-documented context. The subject of the group can be identified both from epigraphy and from its iconographic antecedents, and its version of the subject can be related to a particular strand in the rich later literary representations of the story.
