In 1904–5, French railroad engineer Paul Gaudin conducted a campaign of excavation focusing on the SE sector of Aphrodisias where a villager had found a relief fragment. Gaudin there uncovered (fig. 1) the tetrastyle façade of a fountain, which he incorrectly designated a “gymnasium”. The intercolumniations were decorated with re-used relief panels, which are now on display in the Istanbul Archaeological Museum. The structure was further excavated, studied and reconstructed in 1989 by K. Görkay, but has yet to be fully published. “Gaudin’s Fountain” was built in late antiquity entirely of spolia from other monuments. It thus provides insights into late-antique practices of spoliation and re-use; it also illustrates late-antique renovations undertaken in the city’s final, Christian phase.
