Symbolism might best be considered in terms of revealing and re-veiling. The veil is the protective covering shielding the sacred from the profane, and therefore higher vision can be revealed only to inspired perception. It has always been the task of the initiate to attain this higher vision.
The Villa of the Mysteries or Villa dei Misteri is a well-preserved Roman Villa in Pompeii originally dating from the 2nd century BC. The present layout is thought to be set somewhere between 70 and 60 BC, and the frescoes in the initiation chamber may date to around ca. 60 AD. The villa suffered only minor damage from the eruption of Vesuvius in 79 AD. The room in the villa known as the initiation chamber is decorated with two dozen life-size figures engaged in what is usually considered to be an initiation ritual into the mysteries of Dionysus.
