So dear to heav'n is saintly chastity, That when a soul is found sincerely so, A thousand liveried angels lackey her, Driving far off each thing of sin and guilt, And in clear dream and solemn vision Tell her of things that no gross ear can hear, Till oft converse with heav'nly habitants Begin to cast a beam on th' outward shape.
John MiltonAristotle ... imputed this symphony of the heavens ... this music of the spheres to Pythagorus. ... But Pythagoras alone of mortals is said to have heard this harmony ... If our hearts were as pure, as chaste, as snowy as Pythagoras' was, our ears would resound and be filled with that supremely lovely music of the wheeling stars.
John Milton
