The priests offered sacrifice in the temple of Volupia, the goddess of pleasure, in which stood a statue of Angerona, with a finger on her mouth, which was bound and closed.
[5] Georges Dumézil considers Angerona as the goddess who helps nature and men to sustain successfully the yearly crisis of the winter days.
Dumézil pointed out that the Roman goddesses whose name ends with the suffix -ona or -onia to discharge the function of helping worshipers to overcome a particular time or condition of crisis: instances include Bellona who allows the Roman to wade across war in the best way possible, Orbona who cares for parents who lost a child,[9] Pellonia who pushes the enemies away,[10] Fessonia who permits travellers to subdue fatigue.
On that day the pontiffs offered a sacrifice to the goddess in curia Acculeia according to Varro[12] or in sacello Volupiae, near the Porta Romanula, one of the inner gates on the northern side of the Palatine.
[15] Dumézil sees in this peculiar feature the reason of her being listed among the goddesses who were considered candidates to the title of secret tutelary deity of Rome.
