This is the corner in the outer wall of a second-century BCE house in Delos. You can clearly see that a different type of stone has been used to reinforce the corner, and it is hardly possible to miss how they have been decorated. The phallus played an important apotropaic role in Greco-Roman culture and could be found depicted on many places where it was meant to keep out bad fortune. The mace – if that is what is depicted on the other slab with decoration – could perform a similar role (and, for that reason, could become a symbol for Hercules).
