Gustave Doré, The Empyrean

Empyrean, from the Medieval Latin “empyreus”, an adaptation of the Ancient Greek ἔμπυρος empyrus “in or on the fire (pyr)”, properly Empyrean Heaven, is the place in the highest heaven, which in ancient cosmologies was supposed to be occupied by the element of fire (or aether in Aristotle’s natural philosophy).
