He was a professor of mineralogy of the real body of artillery in Naples. His work of two volumes on the physical topography of Campania has a physical representation of Ischia. No doubt it was the best knowledge of the geology and mineralogy of the island, which had to cross to the fund during his excursions with watchful eyes to the most secluded places. On the small Pera plateau above Casamicciola, where he had his residence, came across the remains of a walled boiler when it was subjected to boiling the raw material. Before this industry was founded in Ischia in 1460, alum had to be imported from Asia Minor.Scipion Breislak
