Averruncus

In ancient Roman religion, Averruncus or Auruncus is a god of averting harm.

Aulus Gellius says that he is one of the potentially malignant deities who must be propitiated for their power to both inflict and withhold disaster from people and the harvests.

Varro[3] asserts that the infinitive verb averruncare shares its etymology with the god whose primary function is averting.

Averruncus may be among the indigitamenta pertaining to another god such as Apollo or Mars,[4] that is, it may be a name to be used in a prayer formulary to fix the local action of the invoked deity.

[6] Averruncus may have also been an aspect of Jupiter or another deity invoked specifically in a protective manner.
