Aquae Cutiliae

Aquae Cutiliae is a mineral spring in Italy, near the modern Cittaducale, 9 miles east of Rieti. The nearby lake was supposed by classical writers to be the central point of Italy, and was renowned for its floating islands, which, as in other cases, were formed from the partial petrification of plants by the mineral substances contained in the water. Considerable remains of baths may still be seen there—they were apparently resorted to by Roman Emperors Vespasian and Titus late in their lifetimes, for both died there.

Its name appears on the Peutinger Table as Aqve cvtillie.
