Abstract

Il folio 735 di Leonardo

Nella prefazione a De Divina Proportione (1498 e 1509) Luca Pacioli loda Leonardo per le sue illustrazioni al libro: disegni di prismi, piramidi, cilindri, sfere, i cinque solidi platonici e sei dei tredici solidi archimedei. Sul folio 735 del Codice Atlantico, tuttavia, Leonardo sembra aver disegnato due altri solidi archimedei che sarebbero stati scoperti molto più tardi, oltre a un rombicubottaedro troncato e forse anche alcuni solidi di Johnson. È generalmente accettato che Leonardo cominciò a studiare i poliedri nel 1496, dopo aver conosciuto Pacioli alla corte di Milano; di conseguenza è plausibile una datazione del folio tra il 1495 e il 1497. Sebbene De Divina Proportione contenga numerosi disegni di poliedri, Pacioli non incluse nel trattato le scoperte di Leonardo, pur lavorando in stretta collaborazione con il vinciano.

Dirk Huylebrouck lectured in Congo and Burundi for twelve years, interrupted by assignments in Portugal and at Maryland University Europe. Next, he taught at the Faculty of Architecture of the KU Leuven (Belgium) and edited the column ‘The Mathematical Tourist’ in the journal The Mathematical Intelligencer. He wrote five books in Dutch, translated into French and/or English): Afrika + wiskunde (2005), De Codes van da Vinci, Bach, pi (2009), België + wiskunde (2009), Wiskunst (2016) and De columns van Professor Pi (2020). Together with Emma Grootveld (Leiden University) and visual artist Rinus Roelofs, he edited the first Dutch translation of De Divina Proportione.
