Krakow, Poland

Polish instrument maker and concert pianist Sławomir Zubrzycki debuted his fully-functional viola organista, created based off of Leonardo’s drawings, at the 5th International Royal Krakow Piano Festival. This festival is the first cultural event dedicated to piano music to take place in Krakow, and the goal of the event is to attract elite pianists and encourage them to perform at this festival.

Nuremburg

Copernicus initially published On the Revolutions of Heavenly Bodies in Nuremburg in 1543, after one of his supporters released an outline of his work to the public in 1541. 

The Vatican Library

The Vatican library still holds the first edition of Trattato Della Pittura (A Treastie on Painting)which is a published collection of Leonardo Da Vinci's notes on the science of painting. The contents of Trattato Della Pittura  were originally written between 1469-1519, organized in the early 1500s, translated into a manuscript in the early 1600s, and was finally published in 1651 by Raffaelo du Fresne. The nature of Leonardo da Vinci's notes made it difficult to organize his work for publication.
