The Opiconsivia (or Opeconsiva or Opalia) was an ancient Roman religious festival held August 25 in honor of Ops ("Plenty"),[1] also known as Opis, a goddess of agricultural resources and wealth.
Since her abode was inside the earth, Ops was invoked by her worshipers while sitting, with their hands touching the ground, according to Macrobius (Saturnalia, I:10).
Although Ops is a consort of Saturn, she was closely associated with Consus, the protector of grains and subterranean storage bins (silos).
The festival of Consus, the Consualia, was celebrated twice a year, each time preceding that of Ops: once on August 21, after the harvest, and once on December 15, after the sowing of crops was finished.
The Opiconsivia festival was superintended by the Vestals and the Flamines of Quirinus, an early Sabine god said to be the deified Romulus.
