In the second and third of the strata which the Calendar offers to the excavator, representing the ordered life of the household and afterwards of the city, we still find much of the same indistinctness. Vesta indeed, the spirit of the hearth-fire, becomes clearly though not personally delineated; so too, but in a less degree, does Janus the spirit of the doorway. Two other groups of spirits also occupy the house; the Lares, who may have been the spirits of dead ancestors duly buried, and the Penates or spirits of the store-chamber; both of them becoming sufficiently clear in the popular conception to be represented by images at a very early period. But in the round of ancient festivals, some at least of the so-called gods, so far as we can guess at their original nature, hardly deserve that name. Liber and Ceres seem to have been originally general names for an ill-defined class of spirits; Robigus is the spirit of the mildew; Consus and Ops are not personalities, but _numina_ protecting the gathered harvest, as Saturnus probably protected the sown seed. The Compitalia was concerned only with the Lares Compitales, spirits of the crossways; in the Paganalia we have but very indistinct information as to the object of worship. The Vinalia, marking a later and more skilled agricultural process, seems on the other hand always to have been clearly connected with Jupiter himself. Thus in the so-called period of Numa, the period of the earlier monarchy and the first organization of the city-state, the religious life of the community had become highly systematized in respect of the cult, of the priest in charge of it, and the _ius_ which governed all the citizens in their relation to the world of divinities. Of any real change however in the character of these divinities, of any approach to polytheism in the way of an increased individuality of conception, of iconic representation, or definite temple-worship, the Calendar then drawn up supplies no certain evidence. There may indeed have been a tendency towards a clearer definition of _numina_, arising from the very fact of the definite organization of prayer and sacrifice, and of the allotment of cults to particular priesthoods or families. There may, even at that early stage in Roman history, have been an influence at work on the Roman mind, coming from Etruria and Greece, where polytheism found its nourishment in works of art and mythological fancy. These are possibilities of which we must take account, but the Calendar has nothing positive to tell us of them.
