Il palazzo arcivescovile di Palermo, da Simone Beccadelli a Giovanni Paternò. Storia e ricostruzione della configurazione quattrocentesca
2021
In the fifties of the fifteenth century, the archbishop of Palermo Simone Beccadelli started the construction of a new archbishop’s palace in an area between the upper stretch of the ancient Cassaro road and the churchyard created along the southern side of the cathedral, whose arrangement had engaged his predecessors since the thirties of the same century. The architectural undertaking, driven by the primary need to create a residence suitable for the rank of the Palermo archibishop’s chair, therefore also assumes a strong urban significance, helping to define the same space of the churchyard and the monumental cathedral complex as a whole. If a first campaign of works would seem to be con…
The Residences of the Kings of Sicily, from Martin of Aragon to Ferdinand the Catholic
2016
In the context of the capital cities of the Aragonese Kindom, it would be necessary to examineand compare the cerimonial practices, behavioral codes, and uses made of the royal residences. At the same time it seems increasingly evident that, during the 15th century, the mobility of the royal court - as well as that of the aristocrats, merchants, and master builders - slowly shaped a modern, homogeneous common language which is currently defined as "Mediterranean Gothic". This paper analyzes the contribution of Sicily through the study of a number of significant buildings : the royal palace of Palermo and the Steri of Chiaromonte , the castle Maniace of Syracuse .
Syphilis 2001 a palaeopathological reappraisal
2002
The origin and subsequent spread of the treponematoses, especially that of venereal syphilis, has been the subject of considerable scientific attention. Various theories were put forth and palaeopathological specimens were used for their validation in recent times. One influential contribution was the paper by Baker & Armelagos in 1988. Numerous new findings and results on both sides of the Atlantic call for a new evaluation of the available osseous material. A review of the recent literature leads to the suggestion of a worldwide distribution of non-venereal treponemal disease since the emergence of Homo and to a first epidemic outbreak of venereal syphilis in Europe of the late 15th and t…
Ville e residenze extraurbane del Quattrocento a Palermo e in Sicilia
2016
With the exception of a few splendid residences inherited from the past and related to the Norman or Swabian courts -which areboth in use and fully operative- the documented cases of new constructions in the 15th century are rare. In a city such as Palermo,the great private gardens were internal to the walled circuit, which allowed for an elitist way of life and matching social behaviours.A compact group of towered buildings constructed during that century in several places throughout the island constitutes, however,a significant phenomenon. In these buildings, which were commissioned by distinguished clients (the Cabrera in Pozzallo, theVentimiglia in Monteleone, the Speciale in Ficarazzi)…
Gas chromatography/mass spectrometry characterization of historical varnishes of ancient Italian lutes and violin
2007
The organic constituents of historical vanishes from two ancient Italian lutes and a Stradivari violin, kept in the Musée de la musique in Paris, have been characterized using gas chromatography-mass spectrometry. Results have been compared with the chromatograms and mass spectra of recent as well as old naturally aged reference materials. The three historical varnishes analyzed have been shown to be oil varnishes, probably mixtures of linseed oil with resins. Identification of diterpenoids and triterpenoids compounds, and of the resins that may have been ingredients of the varnishes, are discussed in this paper.
La formació del plural i la situació del gènere en el «Curial e Güelfa» dins del context del segle XV
2007
We study the situation of plurals in the «Curial e Güelfa» and, by extension, in the Catalan of the 15th century, analyzing particularly the possible subordinating factors of the distribution of plurals -es and -os of masculine words that finish in -s. The situation of plurals helps to confirm the dating of the novel in the middle of the 15th century. On the other hand, in the section of inflection of gender, the presence of forms that confirm the classicism of the novel is evident, as well as some Valencian preferences.
Concept and Treatment of Hydrocephalus in the Greco-Roman and Early Arabic Medicine
2007
In the ancient medical literature hydrocephalus was not often described although its existence and symptomatology were well known. Most detailed descriptions of hydrocephalus including the surgical treatment are extant in the encyclopaedic works on medicine of the physicians Oreibasios and Aetios from Amida from the 4th and 6th centuries AD, respectively. Because of their broad scientific interests, this type of physicians, typical for the late Roman empire, were known as philosophy-physicians (iota alpha tau rho o sigma o phi iota sigma tau alpha iota). They defined hydrocephalus in contrast to our present understanding as a fluid collection excluding abscesses visible as a bulging tumour …
From Illusion to Reality: A Brief History of Robotic Surgery.
2018
Purpose. Robotic surgery is currently employed for many surgical procedures, yielding interesting results. Methods. We performed an historical review of robots and robotic surgery evaluating some critical phases of its evolution, analyzing its impact on our life and the steps completed that gave the robotics its current popularity. Results. The origins of robotics can be traced back to Greek mythology. Different aspects of robotics have been explored by some of the greatest inventors like Leonardo da Vinci, Pierre Jaquet-Droz, and Wolfgang Von-Kempelen. Advances in many fields of science made possible the development of advanced surgical robots. Over 3000 da Vinci robotic platforms are ins…
Conocimiento, traza e ingenio en la arquitectura valenciana del siglo XV
2012
In the last decades historiography of gothic architecture in the Crown of Aragon has focused on buildings monographs, documentary research and technical change in stone building. On the other hand, historians of technology have given special attention to the issue of innovation and its diffusion in the late Middle Ages, considering building techniques as a particular field of research. This essay studies transmission of technical knowledge in building trades in order to explain architectural changes in an outstanding environment of innovation such as the kingdom of Valencia in the 14th and 15th centuries, especially from 1430 onwards. Having account of previous research and some cases of st…
