Numen, pl. numina, is a Latin term. It is used for "divinity", a "divine presence" or a "divine will." The Latin authors defined it as follows. Cicero writes of a "divine mind" ("divina mens"), a god "whose numen everything obeys," and a "divine power" ("vis divina") "which pervades the lives of men." It causes the motions and cries of birds during augury. In his Aeneid, Virgil tells about the how the one-eyed giant, Polyphemus, is blinded: First, Odysseus and his men "ask for the assistance of the great numina" ("magna precati numina"). Reviewing public opinion of Augustus on the day of his funeral, the historian Tacitus reports that some thought "no honor was left to the gods" when he "established the cult of himself" ("se ... coli vellet") "with temples and the effigies of numina" ("effigie numinum"). Pliny the younger in a letter to Paternus raves about the "power," the "dignity," and "the majesty;" in short, the ""numen" of history." Lucretius uses the expression "numen mentis", or "bidding of the mind," where "bidding" is "numen", not, however, the divine numen, unless the mind is to be considered divine, but as simply human will.
