Grist for a future post and nothing to do with the Sarah Plain turkey video:
"At Rome it appears certain that the deity was conceived to be "increased" or "strengthened" (mactus) by the wine or other offering. There was a tradition that originally the offering was not the animal but with grain with salt and wine or milk. Animal sacrifices there almost certainly were on occasion, and in the later period they are familiar; the god received not only the fat (omentum) but also the parts concerned in consciousness---heart, lungs, liverand gall---perhaps in connection with extispicium (prophecy by entrail examination). Grain with salt and wine were before the slaughter sprinkled over the victim, and there was a preliminary offering of incense (i.e. the exudations, sap of trees) and wine. Incense had apparently replaced native grain or aromatic leaves, as e.g. of the laurel with their gum and and oil, pinguis verbena, of which, as we have seen, the "heads of the gods" consisted. "Incense and wine" appear to have been the customary offering in a supplicatio, and we hear that they were applied by the state to private citizens for that purpose at the beginning of the 3rd century B.C. They were also what the dead received, not in vapour as to the gods but directly, as the grease and wine to the bones and the grease to the stones in Homer. Roman deities also received unguent directly. Thus the Arval Brothers "anointed the goddesses"; Lar was anointed; Terminus (the boundary stone) was anointed; upon Pales milk was poured etc."
