Verbum cordis e ministerium vocis. Il canto emozionale di Agostino e le visioni sonore di Ildegarda di Bingen
No full textPartendo dalla concezione della dialettica e del linguaggio in Agostino, lo studio reinterpreta il tema controverso della liceità del canto e la concezione dello iubilus. La seconda parte del saggio indaga sulle funzioni della voce in Ildegarda di Bingen, evidenziando per entrambi gli autori l'importanza della fisicità della voce come mezzo espressivo, distinto dalla razionalità della parola
The Commentario Terzo by Lorenzo Ghiberti and His volgarizzamenti of Vitruvius, Alhazen and the Medieval Perspectivists
No full textThe compilative nature of the Commentario terzo by Lorenzo Ghiberti has posed serious problems to scholars as regards its structure, methodology and aim, which have been long debated. The text is a collection of volgarizzamenti from Vitruvius’ De architectura, Alhazen’s De aspectibus and the medieval optical works by Roger Bacon and John Peckham. This paper focuses on a single aspect of Ghiberti’s Third Commentary, namely his original interventions inserted within the flow of his translations. The first section of the paper recalls the main data concerning the Commentarii and their transmission in the only manuscript copy which conveyed them to us (Florence, BNC, II, I, 333); this is done through a supplementary examination of Giorgio Vasari’s statements concerning this precious witness. Then, a summary of the status quaestionis on the sources of the Commentario terzo introduces the discussion on selected specimens of Ghiberti’s volgarizzamenti from Vitruvius, Alhazen, and the medieval perspectivists. Their textual features illustrate how Ghiberti read, understood and used his scientific and literary sources in order to accomplish his huge effort to expose all aspects of a complex and multifaceted science of vision which, at his time, still spoke a demanding scholastic Latin
La scienza musicale nell’alto medioevo: dalla boeziana mathematica disciplina all’ars musica
No full textNel corso del secolo XI i principi basilari della scienza armonica antica divennero il fondamento di una disciplina ‘emancipata’ dalle sorelle del quadrivio. La scienza della musica divenne un’ars che fondava la prassi del canto liturgico chiarendone il linguaggio, dotandola di opportuni strumenti didattici. Questo legame fra scienza armonica e canto gregoriano fu profondo e creativo, e viene qui esaminato in relazione a tre tematiche di base: 1. la collocazione boeziana della musica fra le scienze del quadrivio e il suo fondamento matematico, 2. la riscoperta altomedievale del De institutione musica di Boezio e la nascita dell’ars musica soprattutto in riferimento all’evoluzione della notazione per rappresentare lo‘spazio matematico’ dei suoni; infine, 3. il monocordo, descritto da Boezio per esemplificare geometricamente i rapporti dei suoni in relazione alla loro altezza ed elaborato nel secolo XI quale cardine della didattica del canto gregorian

Adam Rufus of Exeter, Master and Minor (d. 1234): A State of the Art
No full textThe paper presents an account of the life and works of the almost unknown Friar Minor and Master Adam of Exeter (de Exonia, de Oxonia or Rufus), who was one of Grosseteste’s pupils and a collaborator of Adam Marsh. Adam of Exeter taught the arts at Oxford and entered the Franciscan order about 1229, dying prematurely in 1233/34, while travelling to the Holy Land. Information about his life can be found in Thomas of Eccleston, Grosseteste’ letters, and Thomas of Pavia’s Dialogue on the Deeds of the Holy Friars Minor. Two short works are attributed to Adam in 13thcentury manuscripts: an Anglo-Norman exposition of the Our Father and the Questio de fluxu et refluxu maris; moreover, a summary of Adam’s theory of sound is reported by Master William of Clifford. The paper thus examines Adam’s ideas about tides and sound, which are grounded on his theories concerning the incorporation of light into aerial and watery particles, and their divergencies from Grosseteste’s genuine theories. This comparison also allows for ascribing to Adam the short treatise, De calore solis, commonly held to be by Grosseteste. In addition to these works, the paper considers a set of glosses on Boethius’ De institutione musica and a short work on the rainbow, known by the incipit Inter omnes impressiones, both of which present ideas consistent with Adam’s physics of light. The last section of the paper deals with the Exposition on the Our Father, which is the only theological text ascribed to Adam and was likely his last work
