entheostic is not to be found at OneLook; entheastic seems to be the word.

The entheastic (or such as are agitated by a divine fury). - Thomas Taylor, Plotinus, Introd. (tr. 1794)

But the entheastic character, or he who is under the influence of divine inspiration, unfolding the truth itself by itself concerning the Gods, most perspicuously ranks among the highest imitators. - Algis Uzdavinys, Golden Chain: An Anthology of Pythagorean and Platonic Philosophy (2004)
