we see that the divinity concerned with the sacrifice is also included. The rite was
doubtless addressed to a number of interested divinities, from which those sacrific-
ing sometimes extracted a particular figure that was more directly relevant. We might
suppose that it involved a summary of the rites which were to follow, by which the
intention was also expressed. As such, libation is one of the key subjects in images
of sacrifice, and comes to signify “pietas.”
After this introductory ritual, the sacrificer proceeded to the immolation (immo-
latio) of the victim (see Latte 1914). In the “Roman” rite, he scattered the back of
the victim with salted flour (mola salsa, from which the term in-molatiois derived),
pouring a small amount of wine on the animal’s forehead, and, finally, passed the
knife over its back. From the prayers that accompanied immolation and the com-
