empyrean

taivaallinen, mahtava

taivas The region of pure light and fire; the highest heaven, where the pure element of fire was supposed by the ancients to exist: the same as the ether, the ninth heaven according to ancient astronomy.
(RQ:Milton Lost)

So sung they, and the Empyrean rung, / With Halleluiahs:

the deep-domed empyrean / Rings to the roar of an angel onset

The very empyrean seemed to be a secret.

In th’empyrean heaven, the bless’d abode, / The Thrones and the Dominions prostrate lie, / Not daring to behold their angry God.

Yet upward she the goddess incessant flies; / Resolv’d to reach the high empyrean Sphere.

Lispings empyrean will ii sometimes teach / Thine honeyed tongue.
