Lake of Cutilia
Lake Cutiliensis (modern Lago di Paterno) is a lake in the municipality of Castel Sant'Angelo, near the ancient Reate, now Rieti. In antiquity it was sacred to the Sabines. Varro, who came from Reate, called it the "navel of Italy". Overview. The lake took its name from the town of Cutiliae or Cutilium, which was on its shores at the foot of a mountain. In his work "De Lingua Latina", Varro writes that it was inhabited by the "lymphae commotiles" or "commotiae", nymphs whose presence is explained by the floating island found there. Pliny says much the  same. In his book about theories on the origin of the Saturnalia, Macrobius narrates that the Pelasgians, one of the earliest people who inhabited Latium, had been expelled from their original territory and, having wandered through many places, at last arrived in great numbers at Dodona in Epirus. There they asked the local oracle where they could settle permanently. The oracle's "responsum" was that they should go to the Saturnian land of the Siculi and Aborigines, to Cutilia, where there was a floating island. They were to expel the locals, then sacrifice a tenth of whatever they had taken  as booty "(praeda)" to Phoebus and to Hades. Human captives were explicitly included: they were instructed to "send the heads and "phota" ('lights', also 'lives') to the father". Having followed the instructions of the oracle, they arrived at Lake of Cutilia and occupied the island. This island was formed by overgrown plants and its growth had been favoured by the murkiness of this marsh, as was said to have been of Delos. After expelling the Siculi the Pelasgians occupied the lands. They offered as a sacrifice to Apollo the tenth part of the prey and built a shrine to Dis  and an altar to Saturn, naming the feast "Saturnalia" after him. They continued for a long time to perform human sacrifices in order to offer heads to placate Dis and Saturn, until Hercules came to those lands and persuaded their descendants to replace the human heads with masks and to honour the altar of Saturn with lamps, since "phota", "lights," may mean "lamps" as well as the "light" of men's lives. The waters of a spring near the lake were extremely cold and supposed to be medicinal: they were considered good for the stomach and nerves. They acted by  a kind of suction the feeling of which approached that of a bite. The Emperor Vespasian used to come every summer to drink the waters, and he died there. His son emperor Titus too died there. The place was an enclosed area ("locum saeptum": fenced place) considered sacred and was inhabited by an oracle influential among the Sabines. Sometimes the Sabine migrations known as the "ver sacrum" started from this place: a famous instance is that of the seven thousand "sacrales" led by Comus (or Cominus) Castronius who founded Bovianum following the steps of an ox, thus giving rise to  the Samnite nation.
