Mercury, the inventor of the lyre, is said to have derived the idea of
it from the harmony of the spheres. This astral music, apprehended by

contemplation of the Creator, they would have spoken fitly; for there
is truly joy without end, eternity abiding for ever without weariness,
and the mere contemplation of the Divinity produces such happiness
that nothing can surpass it. This Being furnishes the true
immortality; this heaps delight upon delight; and as outside of Him no
creature can exist, so without Him changeless happiness cannot
be[273].
