"So great beginnings, in so green an age,
Exact the faith which I again engage.
Thy mother all the dues shall justly claim,
Creüsa had, and only want the name.
Whate'er event thy bold attempt shall have,
'Tis merit to have borne a son so brave.
Now by my head, a sacred oath, I swear,
(My father used it,) what, returning here
Crowned with success, I for thyself prepare,
That, if thou fail, shall thy loved mother share."
