THE THERMAE OF TREBULA
The thermal building of Trebula Balliensis bringed to light
in 1976 during the construction of the road that joins the
Campole locality with the main road; the thermae are at North
outskirts of Treglia. During the named construction a substantial
part of them was illegally demolished; so, a remarkable part
of the thermae is under the roadway. The thermal kept environments
have a surface that measures 150 square metres (150 mq). By
observing the composition of the wallings we can note
two different kinds of building
: the first is a masonry
made by tufaceous tiles, the second is a masonry made by tufaceous
tiles mixed with bricks and tiles. Therefore, the thermal
building reached noeadays turns out to be the refurbishment
of a preexisting building;
particularly, we can recognize
two different building stages that are simply synthesized

Now we try to assign to thermae an exact chronological
sphere. The building tecniques wich were utilised are the
simple and mixed masonry, often using again the salvage. On
these grounds we can date them at late imperial age.
In this context is useful to make the following digression
about the dating of the thermae of Trebula. Plinius the Old,
in his work "Naturalis Historia (3, 64)", referring to Trebula,
uses the "Trebulani cognomine ballienses"
sentence. Plinius lived from 24 A.D. to 79 A.D. because he
died at Pompei, during the Vesuvio's eruption wich buried
Pompei and Ercolano. All this shows that, in this time, Trebula
had already the thermae, deserving the "Balliensis" appellative.
Therefore, doesn't dating of the thermae at costantinian age
contradict Plinius? No, it does not. It's obvious that the
thermae named by Plinius aren't those excavated in 1976. This
means that the thermae named by Plinius should be in other
place or the costantinian thermae should be a total remaking
of the thermae named by Plinius.
