Between two worlds Life hovers like a star,

'Twixt Night and Morn, upon the horizon's verge.

How little do we know that which we are!

How less what we may be![766] The eternal surge

Of Time and Tide rolls on and bears afar

Our bubbles; as the old burst, new emerge,

Lashed from the foam of ages; while the graves

Of Empires heave but like some passing waves.[767]
