For as a glass is an inanimate eye,

And outward forms embraceth inwardly,

So is the eye an animate glass, that shows

In-forms without us; and as Phœbus throws

His beams abroad, though he in clouds be clos'd,

Still glancing by them till he find oppos'd240

A loose and rorid vapour that is fit

T' event[60] his searching beams, and useth it

To form a tender twenty-colour'd eye,

Cast in a circle round about the sky;
