The Stoibadeion contains a rectangular platform containing a statue of Dionysus, which was flanked by two actors impersonating Papposilenoi.
Two pillars, one on each side of the platform, each once supported a huge phallus, as a symbol of Dionysos.
The southern pillar is decorated with relief scenes of a Dionysiac circle.
The southern pillar bears an inscription that it was erected ca.
by a Delian named Carystios in celebration of a victorious theatrical performance he sponsored.
