The present work is the result of a research started with Studio Glowarp in partnership with Academy of fine arts in Naples. To achieve and prove such result, in this project it was used a particular technique of augmented reality called video mapping with the aim of reevaluating the replica in scale of the world famous "David" by Michelangelo, sculpture present in the same building. The installation (projected the 27th february), entitled "Michelangelo's David", is the demonstration of how new technologies can play a fine role for the enhancement of cultural heritage of a nation it got the patronage of UNESCO that has entitled the 2015, International Year of Light and of the technologies based on light (IYL). Thanks to the art of video mapping the rediscovery of this sculpture has achieved a great result, success based not only on the reevaluation of the work of art but also because such performance touched the soul of the audience leaving them in an ecstatic state. Thanks to the live event a large number of the audience for the first time came to know the existence of this replica work present in the building of the Academy of which they totally ignored the presence. Another aim of the project is that of showing the artistic potentiality of the mix among analogical and digital media and how video mapping could be also considered as an extension of the painting. A reevaluation of cultural heritage through video mapping that is perfect for the standards expected by the law in matter of cultural properties in Italy. The action of reevaluation is not to be considered as an attempt to substitute the peculiar value of the work itself. Part of this project will be show in a website.
