a prophetic nymph or Sibyl, to whom in the neighbourhood of Tibur a grove was consecrated, with a well and a temple. Near it was the oracle of Faunus Fatidicus. (Verg. A. 7.81, &c.; Hor. Carm. 1.7.12; Tib. 2.5. 69.) Lactantius (De Sibyll. 1.6) states, that the tenth Sibyl, called Albunea, was worshipped at Tibur, and that her image, holding a book in one hand, was found in the bed of the river Anio. Her series, or oracles, which belonged to the libri fatales, were, at the command of the senate, deposited and kept in the Capitol. The small square temple of this Sibyl is still extant at Tivoli. Respecting the locality, see Kephalides, Reisen durch Italien, i. p. 125, &c.
