For Ops see on Aug. 25, when the sacrifice was in the Regia, the significance of which I endeavoured to explain. Here it is ‘ad forum,’ which has lately aroused a little unfruitful dispute. Is the temple of Saturn meant, which was also described as ‘ad forum’ in the same calendar? This is still the view of Mommsen[1208], who seems to hold the old opinion that there was a sacellum Opis attached to the aedes Saturni, or that this aedes was dedicated to both deities[1209]. H. Jordan made up his mind that ‘ad forum’ meant the Regia[1210]; but this is not supported by any similar entry in the _Fasti_. Aust and Wissowa believe that Ops had a separate temple ‘ad forum,’ of which all traces are lost, as has happened with many others[1211]; and the latter, as we have already seen, disbelieves in any connexion between Saturnus and Ops, attributing it entirely to Greek influence. However this may be, the one interesting fact about the temple—or whatever it was—is that it was ‘ad forum.’ The conjunction of Saturnus and Ops at this place and time must surely indicate some connexion of function between the two. But what it was is not discoverable; under Saturnalia I have merely suggested the direction in which we may look for it. XII (ANTE CAES. X). KAL. IAN. (DEC. 21). NP. DIVA[LIA]. (MAFF. PRAEN.) Praen. adds a terribly mutilated note, which Mommsen thus fills up from stray hints in Varro, Pliny (following Verrius), and Macrobius[1212]: FERIAE DIVA[E ANGERONAE, QUAE AB ANGINAE MORBO] APPELL[ATUR, QUOD REMEDIA EIUS QUONDAM] PRAE[CEPIT. STATUERUNT EAM ORE OBLIGATO] IN AR[A VOLUPIAE, UT QUI NO]SSET N[OMEN] OCCUL[TUM URBIS, TACERET. S]UNT TAMEN, [QUI FIERI ID SACRU]M AIUNT OB AN[NUM NOVUM; MANI]FESTUM ESSE [ENIM PRINCIPIU]M [A]NNI NOV[I]. The date given by Pliny and Macrobius proves that Angerona was the deity of the Divalia; but the etymology of the latter is useless, and the statement of Pliny as to the statue with the mouth gagged and sealed fails to give us any clue to the nature or function of the goddess[1213]. Angerona is, in fact, the North Pole of our exploration: no one has ever reached her, and probably no one ever will. The mention of Volupia by Macrobius gives no help; she is only elsewhere mentioned as one of the numina of the Indigitamenta by Augustine[1214]. The only possible clue is that of which Mommsen has taken advantage in the very clever completion of Verrius’ last words, viz. the fact that this day (21st) is the centre one of the winter solstice. He here even allows himself an etymology, and derives Angeronalia ‘ab angerendo, id est ἀπὸ τοῦ ἀναφέρεσθαι τὸν ἥλιον’: quoting Plutarch (_de Iside_, ch. 52) for similar Egyptian ideas of the sun’s birth at this time. Though the etymology may be doubtful, the inference from the date of the festival is certainly acceptable, in the absence of anything more definite: and the ‘Praenestine fragments’ clearly suggest the word ‘annus.’
