Morrai si l'empia tua testa

English Libretto or Translation:

Rodelinda
But tremble thou, vile counsellor, for fear,
unworthy minister, thou`lt have cause to fear,
I, as thy judge, thee, traitor, will arraign
and thou ́rt as sure to die as I to reign.
Yes, thou shalt die – I’ll make that head
the step, by which to thrones I’ll tread.
I`ll claim it of my new-made spouse,
he’ll grant it to cement our vows.
I know no gift will please me more
that he can grant, or I implore.
Yes, thou etc.
