Are we sure that panel means Forum?
In general, 'Forum' can mean 'panel' in the sense of a public discussion. In this case this isn't a very natural interpretation, however. So, 'the Forum (Forum Romanum) at night' would be a better translation.
At least much more beautiful.
Now I know a thing more about English, thanks wataya! :)
Technically, this isn't a sentence so there shouldn't be a period. Not that I'm being picky as the translations or anything! :)
