Vacuna

She was mainly worshipped at a sanctuary near Horace's villa (now in the commune of Licenza), in sacred woods at Reate, and at Rome.

Pomponius Porphyrion calls her incerta specie (of an uncertain kind) in his commentaries on Horace.

Renaissance authors[1] and Leonhard Schmitz[2] state 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.

The etymology of her name is linked to lack and privation, and Horace appears to call upon her in favour of a friend to whom one of his epistles is addressed.

[3] Ovid mentions rites linked to sacramental fires with attendants either standing or sitting, that he compares to olden ceremonies observed on behalf of Vesta, without any suggestion of field work nor absent dear ones.
