Hadrian Quote

Ah! gentle, fleeting, wav'ring sprite,
Friend and associate of this clay!
To what unknown region borne,
Wilt thou now wing thy distant flight?
No more with wonted humour gay,
But pallid, cheerless, and forlorn.

J. W. Duff (ed.) Minor Latin Poets (1934); translated by Byron as 'Adrian's Address to His Soul When Dying'
