Empyrean
In ancient cosmologies, the Empyrean Heaven, or simply the Empyrean, was the place in the highest heaven, which was supposed to be occupied by the element of fire. The word derives from the Medieval Latin empyreus, an adaptation of the Ancient Greek empyros, meaning "in or on the fire ".
The Empyrean was thus used as a name for the firmament, and in Christian literature for the dwelling-place of God, the blessed, celestial beings so divine they are made of pure light, and the source of light and creation. Notably, at the very end of Dante's Paradiso, Dante visits God in the Empyrean.
The word is used both as a noun and as an adjective, but empyreal is an alternate adjective form. The scientific words empyreuma and empyreumatic, applied to the characteristic smell of the burning or charring of vegetable or animal matter, have the same Greek origin.
