The Extension & Octagon

From the Greek temple, the tunnel today extends forward to an octagonal room that was clearly in its final phase a hot Roman bath, as its hypocaust floor is easily visible. In the pictures the purple line is where a tunnel exists today and the blue one is a probable original tunnel, although if this was human height, some kind of structure similar to the area of the Greek Temple would have been necessary. The later extension to the octagon is not human height, it’s much lower.

The plastic cups and other litter in the trench were left by a film crew and had sat there for years. It was removed by Peter Knight and Graziano Ferrari in 2014.
 

A logical extension on the same line as the Great Antrum would have exited to a room precisely where there is a bricked in rounded arch. Investigation behind that arch would determine if the remains of a tunnel are there or not.

Ritual or no ritual?

Virgil, who lived nearby, wrote his famous Aeneid where Aeneas prays to be allowed to descend to the underworld, so that he can visit his dead father. Descents to the underworld, with ritual death and rebirth for the individual, were part of the Greek Mysteries and Virgil was a known initiate, as was Augustus. So we know The Mysteries were observed in Roman times, in fact until the collapse of the Roman Empire. This could well be the site, by The Mysteries and Mythology will be explored on another page.

The later extension was, in its last phase, a Roman bath, the supports for a hypocaust are clearly, and yet there is evidence again that might make us pause and think.

The entrance itself looks as if it was quite important at one time – too elaborate for steam entering under the hypocaust floor. Was this once a passage for humans?

Opposite the entrance on the left is an oblique slot, which directly faces the entrance – surely no accident.

Tunnel extensions

The blue line of the Great Antrum is possibly where an extension of the main tunnel exited to a room where a bricked up archway is visible.

The purple line is a later diversion, which involved cutting off a corner of the room.

The curious Slot

Why is there this narrow gap in the wall? It isn’t square to it – it goes through at angle, so it faces precisely opposite the tunnel entrance. Were these ritual buildings before the octagon was made into a bath house?
