In Händel's *Giulio Cesare in Egitto*, the libretto to Cleopatra's famous aria reads:

> 
> E pur così in un giorno 
>    
>  perdo fasti e grandezze? Ahi fato rio! 
>    
>  Cesare, il mio bel nume, è forse estinto; 
>    
>  Cornelia e Sesto inermi son, né sanno 
>    
>  darmi soccorso. O dio! 
>    
>  Non resta alcuna speme al viver mio. 
>    
>  Piangerò la sorte mia, 
>    
>  sì crudele e tanto ria, 
>    
>  finché vita in petto avrò. 
>    
>  Ma poi morta **d'ogn'intorno**
>   
>  il tiranno e notte e giorno 
>    
>  fatta spettro agiterò. 
> 
> 
> 

The opera was written during the baroque period at the end of the 18th century, but I'm assuming the libretto is older, though not very much older. The author of the libretto is Nicola Francesco Haym, who based them on a libretto by Giacomo Francesco Bussani, whose text was used no earlier than 1676. Am I assuming wrongly that this is unlikely to still be old Italian? What, then, is the Italian of this era called and what is the appropriate translation for the phrase? The translations I have seen (French, English, and German) simply do not translate the phrase.

You may wish to listen to a recording of the [aria from 'Ma poi morta'](http://youtu.be/b86ALmacV3U?t=3h13m12s) onwards. I retrieved the libretto from [Stanford Opera Glass](http://opera.stanford.edu/iu/libretti/giulioces.htm), which is usually a reliable source.
