Skill’d to correct the vices of the sky, 500

And taught already how to each extream

To bend your life. But should the public bane

Infect you, or some trespass of your own,

Or flaw of nature hint mortality:

Soon as a not unpleasing horror glides 505

Along the spine, thro’ all your torpid limbs;

When first: the head throbs, or the stomach feels

A sickly load, a weary pain the loins;

Be Celsus call’d: The fates come rushing on;
