This relief, set over the courtyard fountain, belongs to a series of eight Maenads (the seven others were unearthed separately in Rome in 1908 and are now in the Museo Nazionale Romano, Rome). Together, they formed a cylindrical frieze of exuberantly dancing women that was probably the base of a tripod dedicated to Bacchus. Maenads were female followers of Bacchus who danced themselves into orgiastic frenzies.
