Gesualdo Osservazioni critiche sopra la storia della Via Appia di Pratilli p. 7 (Naples, 1754).
Some additional discoveries were described by Marc Antonio Boldetti in his Osservazioni, published in 1720; but, writing in the interests of the Roman Church with an apologetic, not a scientific object, truth was made to bend to polemics, and little addition to our knowledge of the catacombs is to be gained from his otherwise important work.
Among the older works are: Bosio, Roma sotterranea, Severano's edition (1632), and Aringhi's edition (1651); Boldetti, Osservazioni sopra i Cmiteri dei santi martini (Rome, 1720); Bottari, Sculture e pitture sagre, &c. (Rome, 1 7371 754); Seroux d'Agincourt, Histoire de l'art par les monuments (Paris, 1823; German ed., 1840); G.
Zaccagna, " Riassunto di osservazioni geologiche fatte sul versante occidentale delle Alpi Graie," Boll.
These discoveries, subsequently amplified in his Le Stelle cadenti (1873) and in his Norme per le osservazioni dellestelle cadenti dei bolidi (1896) gained for him the Lalande prize of the Academy of Sciences, Paris, in 1868, and the gold medal and foreign associateship of the Royal Astronomical Society in 1872.
In 1811 he produced a valuable essay entitled Memoria mineralogica sulla Valle di Fassa in Tirolo; but his most important work is the Conchiologia fossile subapennina con osservazioni geologiche sugli Apennini, e sul suolo adiacente (2 vols., 4to, Milan, 1814), containing accurate details of the structure of the Apennine range, and an account of the fossils of the Italian Tertiary strata compared with existing species.
