_Page 146._ The facts about the descent of the Turks upon Otranto in 1480 will be found stated briefly in all the histories. But they are sufficiently curious to make it worth while to consult the admirable and detailed report made to Ludovic Sforza, Il Moro, by the commissary who served him in his capacity as Duke of Bari. As ruler of the chief Apulian coast town, Il Moro was of course painfully anxious for exact information about the proceedings of the Turks. The report will be found in volume vi. of the _Archivio Storico_, published by the "Società di Storia Patria," of Naples. _Page 150 et seq._ The story of Conradin's expedition and death is told best in von Räumer, _Geschichte der Hohenstaufen_. It will be found also in Amari, _La Guerra del Vespro_. The two historians report the circumstances of Conradin's death with some differences of detail, having relied on different chronicles. The variations are not essential. _Page 158._ Details concerning the examination of Conradin's tomb will be found in Filangieri, _op. cit._ _Page 161._ For the story of Mas'aniello's revolt I have followed Sign. Gabriele Tontoli, _Il Masaniello, overo Discorsi Narrativi, La Sollevatione di Napoli_, printed at Naples in 1648. I selected this work (1) because it is rare; (2) because it is full of detail; (3) because it is the narrative of an eye-witness. _Page 178._ The literature of Vesuvius is immense. As general references, I can only indicate again the works named in the note on page 21. _Page 182._ Braccini's narrative was published at Naples in 1632 under the title _Dell'Incendio fattosi nel Vesuvio_. _Page 190._ Palmieri's account has been translated. _The Eruption of Vesuvius in 1872_ (London, 1873). _Page 196._ Herculaneum. Once more it is well to refer to Beloch, _Campanien_. _Page 201 et seq._ The work of Signori Comparetti and de Petra was published at Turin in 1883, under the title _La Villa Ercolanense dei Pisoni_. It is one of those monuments of patient, well-directed learning and research which fill one with high hopes for the future of Italian scholarship. I presume the British Museum acquired its copy shortly after publication. I may add that I cut its pages in July, 1900--a fact that says worlds about British scholarship. _Page 209._ The translation of Mau's _Pompeii, its Life and Art_, was published at New York in 1899. _Page 217._ The only works worth mentioning about the pictures at Pompeii are those of Helbig, _Untersuchungen über die Campanische Wandmalerei_ (Leipzig, 1873), and his earlier _Wandgemälde_ (Leipzig, 1868). A summary of Helbig's conclusions will be found in _Promenades Archéologiques_, by Gaston Boissier (Paris, 1895). _Page 223._ On Stabiæ a work comparable only to that cited above on Piso's villa has been written by Signor Michele Ruggiero, _Degli Scavi di Stabia_ (Naples, 1881).
