REGILLUM (Ῥήγιλλον), a town of the Sabines mentioned by several ancient writers as the place of residence of Atta or Attius Clausus, who migrated to Rome about B.C. 505, with a large body of clients and followers, where he adopted the name of Appius Claudius and became the founder of the Claudian tribe and family. (Liv. 2.16; Dionys. 5.40; Suet. Tib. 1; Serv. ad Aen. 7.706.) About 60 years afterwards C. Claudius, the uncle of the decemvir Appius Claudius, withdrew into retirement to Regillum, as the native place of his forefathers ( antiquam in patriam, Liv. 3.58; Dionys. 11.15). The name is not noticed on any other occasion, nor is it found in any of the geographers, and we are wholly without a clue to its position.
