		| Abstract: | 
		In the fall of 1604 a very brilliant Supernova lighted up, becoming a central subject for the astronomical debates of the time. Today that explosion is recalled with the name of Kepler's Nova, and really the German astronomer dedicated a large amount of energy in studying this unusual phenomenon. In this paper we want to outline how the book he published in 1606, his De Stella Nova, stands as a monument to accurate observations and geometrical demonstrations. |
