Italian and foreign theatres over the next ten years. During this time De Giosa was also active as a teacher at the Conservatory of San Pietro a Majella and in organizations dedicated to the encouragement of young musicians and composers. De Giosa spent his last years in Bari under the care of his doctors and relatives. By June 1884 he was reported to be suffering from insanity and severe physical debilitation. He no longer recognized the friends who came to visit him and frequently invoked his old teacher, murmuring "Donizetti!... student of Donizetti... I die looking up to the sky!". He died in July 1885 at the age of 66 and was buried in the city's Cimitero Chiesa Madre. The street Via Nicola de Giosa which ends at the Teatro Petruzzelli was named in his honour. He is also commemorated with a large statue which stands in the foyer of the Petruzzelli. It had survived the fire which virtually destroyed the original building in 1991.
