La Biblioteca di Ginevra esporrà il "Divina Proportione", trattato sulle applicazioni della sezione aurea (il numero irrazionale inizia con 1.61803398875...) realizzato da Fra' Luca Pacioli nel 1498 e illustrato con 60 tavole di Leonardo da Vinci. Un preziosissimo scritto del quale furono realizzate tre copie: una è andata persa, una è a Milano e una nella città di Calvino dal 1796.
Un manoscritto eccezionale conservato a Ginevra dal 1756
Il prezioso manoscritto sarà eccezionalmente presentato al pubblico i prossimi 1 e 2 marzo all'Espace Ami Lullin situato nello stabile dell'Università "Bastions". Venerdì è prevista una tavola rotonda durante la quale gli esperti daranno una risposta a una domanda finora non del tutto evasa: i disegni sono stati realmente realizzati dalla mano del genio toscano citato nel trattato? Sabato la presentazione con entrata libera, ma il numero dei posti è limitato.
Il trattato partirà in seguito per Roma dove sarà esposto una mostra temporanea dedicata a Leonardo.
Da venerdì sarà disponibile in forma elettronica su e-codices.ch, la biblioteca virtuale dei manoscritti conservati in Svizzera.
