The Diapason closing full in Man.”
In the centre of the universe (he taught) there was a central fire, the principle of life. The central fire was surrounded by the earth, the moon, the sun, and the five planets. The distances of the various heavenly bodies from one another were conceived to correspond to the proportions of the musical scale. The heavenly bodies, with the gods who inhabited them, were supposed to perform a choral dance round the central fire, “not without song.” It is this doctrine which Shakspeare alludes to when he makes Lorenzo teach astronomy to Jessica in this fashion:
“Look, Jessica, see how the floor of heaven
Is thick inlaid with patines of bright gold!
There’s not the smallest orb that thou behold’st
But in his motion like an angel sings,
Still quiring to the young-eyed cherubim;
Such harmony is in immortal souls!
But whilst this muddy vesture of decay
Doth grossly close it in we cannot hear it.”
