Vacuna
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. (Fasti By Ovid. Pindar) From the Scholiast on Horace, we also learn that some identified her with Diana, Ceres, Venus, or Minerva.
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom Fasti By Ovid
It was once the custom to sit on long benches by the fire,
And believe the gods were present at the meal:
Even now in sacrificing to ancient Vacuna,
They sit and stand in front of her altar hearths.
Something of ancient custom has passed to us:
A clean dish contains the food offered to Vesta.
See, loaves are hung from garlanded mules,
And flowery wreaths veil the rough millstones.
