The two views in question are signed by Francesco Fergola, a painter, known for his work as a landscape painter, born in Naples in 1801. Son of the painter Luigi and brother of Salvatore, he is not to be confused with his nephew of the same name, also a painter, and his brother, also of the same name, an internationally renowned engineer and geographer. His original and particular approach, less influenced by the Posillipo school than his brother, appears more linked to his father's Hackertian way.
