Help identifying italian paintings of the XVIII Century

I need some help identifying some italian paintings of the late XVII/early XVIII Century. The first is this painting, from the late XVII Century, found in this site. The second is this one, from the early XVIII Century, that I found on this article

What do you want to know? Can't say anything about the first one.
But the second based on my very limited Italian seems to be by some guy called Alessandro Piazza depicting the Ruspoli Regiment receiving papal blessings before departing to battle against the Austrians. Painting notable because it includes Händel who was in Rome at the time.
