a Sabine divinity identical with Victoria. She had an ancient sanctuary near Horace's villa at Tibur, and another at Rome. The Romans however derived the name from Vacuus, and said that she was a divinity to whom the country people offered sacrifices when the labours of the field were over, that is, when they were at leisure, vacui. (Schol. ad Horat. Epist. 1.10. 49; Ov. Fast 6.307; Plin. Nat. 3.17.) From the Scholiast on Horace, we also learn that some identified her with Diana, Ceres, Venus, or Minerva.
