(ANSA) – Milan, September 11 – Visitors can now tap through Leonardo Da Vinci's largest bound set of drawings and writings, the Atlantic Codex, on their smart phones, tablets and computers. The Atlantic Codex consists of 12 volumes and 1119 pages of Leonardo Da Vinci's work from 1478 to 1519. It covers subjects ranging from weaponry to musical instruments, flight, mathematics and botany. Twenty-four exhibits on the codex scheduled through 2015 will become available at the website www.insidedavinci.com. The 17th century Catholic library-museum that owns the codex, the Biblioteca Ambrosiana, presented the initiative on Tuesday in Milan. The project offers virtual, 3D navigation of exhibited works, explanations, supplementary materials developed by Italian publisher DeAgostini, and audio commentary. The first two exhibits to be made available online are 'Fortresses, ramparts and cannons' and 'The library, time and friends'. Access to interactive tours costs 2.99 euros and is valid for six months. The Biblioteca Ambrosiana also presented Tuesday the exhibit 'Anatomy of man and anatomy of the earth'. The exhibit marks the 13th series of leaves selected from the Atlantic Codex for show. It illustrates an analogy Leonardo traced between the human body and the earth as organisms endowed with life. The exhibit, open until December 9, is divided into two parts. The first is located at the Biblioteca Ambrosiana. The second is in the Sacrestia del Bramante, located in the Basilica of Santa Maria delle Grazie, which is part of the same historic Domenican sanctuary that houses Leonardo Da Vinci’s Last Supper.
