Prospectiva Pingendi, Prospectiva Fingendi. For a History of the Different Rules of Practical Perspective
Get PDFThe method of perspective representation has consolidated over time, up to its complete formalization, through a series of important and complementary achievements both in the scientific and artistic fields. While the study of the laws of ancient optics, combined with practical experimentation, slowly contributed to the rigorous formalization of the method in Renaissance intellectual circles, the workshop practice required operational rules that quickly and easily enabled artists to produce images in which the depth of the space and the three-dimensionality of the subjects it contains were evident.The study presented here intends to focus attention on the procedures practiced by artists, with particular attention to perspectives rules that really weren’t , in the scientific sense of the term, but which contributed to establish a shared andwidespread basis for the development of sensitivity of seeing and representing in perspective, in the intimate and labile boundary between prospectiva pingendi and fingendi
Chapter Prospettiva e visualità: il volere della ragione, il valore dell’intenzione
Get PDFThe 43rd UID conference, held in Genova, takes up the theme of ‘Dialogues’ as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with ‘others’, which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, “dialogue” as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title ‘translated’ into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences
Il Vignola e le sagme. Una prospettiva dinamica
No full textIl trattato “Le due regole della prospettiva pratica” di Jacopo Barozzi da Vignola, nella pregevole edizione di Egnazio Dati, fornisce informazioni preziose sull’evoluzione della rappresentazione prospettica, sia per gli approfondimenti teorici originali, sia per l’estesa esposizione di questioni di natura pratica. Il presente studio affronta in particolare l’analisi e l’illustrazione della prospettiva realizzata con l’utilizzo delle sagme, un singolare e poco noto procedimento collegato alla seconda regola, in grado di conferire alla rappresentazione prospettica un notevole ed inedito dinamismo
