Aquae Caeretanae were large and elaborate ancient Roman thermal baths at Pian della Carlotta, about 2 km north west of the village of Sasso in the province Lazio.
Livy (59 BC-17 AD) also noted[4] that wonders occurred during the Second Punic War which led to the red colouring of the waters of the fons Herculis at the Aquae Caeretanae as though mixed with blood.
[6] The second dedication, on a marble table decorated with leonine protomes from no later than the middle of the first century AD, is by a certain Lucilius Pontilius and also refers to Jupiter.
Today, two large rectangular rooms, the calidarium and tepidarium, are visible, both equipped with a swimming pool, the first surrounded by twelve pillars covered with marble.
These were surrounded by no less than three rows of marble seats and with beautiful mosaics with blue, green, yellow, black and red glass-paste tesserae which depicted an explosion of flowers on a white field.
