Martin Leutzsch, Die Wahrnehmung sozialer Wirklichkeit im “Hirten des Hermas” (Gottingen: Vandenhoeck & Ruprecht, 1989), pp. 31–39, lists from ancient Greco-Roman literature nine scenes of mortal man observing bathing goddesses, eighteen references to cultic washing of goddess statues and pictures, and nine erotic scenes, from other ancient texts, that portray women bathing, among them David and Bathsheba and Susanna and the elders.
