This statue was made by Salvatore Albano, an Italian sculptor from the 19th century. The title of the work is The Fallen Angels and it was done in two parts; the base is from 1883 and the marble part is from 1893. This statue is owned by the Brooklyn Museum in New York. It is one of the biggest art museums in the United States along with MoMA and the Metropolitan Museum of Art.
"At the apex of this sculptural group, a sword-wielding Satan struggles alongside his rebel angels against God and his army (both absent) in heaven. -- "
I am quite confident that the Brooklyn Museum has situated this statue intentionally in the lobby under those windows that are letting the light from sky (heaven) to descend on The Fallen Angels, simulating the army of heaven and their power over this small group of rebels.
