According to Horace, the Nones of December are associated with Faunus. Since the early part of December is also the time for the movable or feriae conceptivae celebration by women for the Bona Dea, the 'Good Goddess', most likely Fauna, the rustic festival to Faunus on the Nones may be interrelated. We are informed that those who celebrated the Faunalia danced in triple measure - presumably the same or at least similar to that of the Salii in honour of Mars. Faunus appears in general to be a rustic version of Mars in conncection with fertility and concern with the earth. Faunus' temple was to be found on the Tiber Island (though its dedication day was the Ides of February), but the Fasti Amiternini and Fasti Antiates Maiores both indicate Tiberino in insula for the 8th of December - the latter also including the Greek goddess Gaia, and this sacrifice to the Tiber (and Gaia) from the island may be connected to the Faunalia of this time. Tiberinus would of course be a manifestation of Janus in his capacity as a river-god. Mars, as the protoype of Faunus, connects with Janus especially through his alter ego figure of Quirinus. In all, the associations are murky but suggestive of the organic plasticity of godhead in Roman consciousness and the concern with ritual purification and the earth as a prelude to the Latin yule and the rebirth of the sun.
