The firt main result of this work can be estated as follows: The architectural setting of the Labyrinth, the Transept, the Apse, The Ambulatory and the Rose window of the main facade of the Chartres Catedral are defined following the astronomical pattern of the millenary Catasterismi of the egyptian God Isis and Notre-Dame. In particular, we can see that a linear correlation exists between the stars configuration of the declinations of Isis deity catasterismi –Elthor, Spica, Isis, Sirio and Adhara from the constellations of Tauro, Virgo and Canis Maior– in astronomical time J1200.0, when Chartres Catedral was build, and the declinations of the design of the cathedral with probability 1-k=0.9994 and coefficient of correlation of Pearson Rpq=0.99. This linear correlation makes that the declinations produced by the building parameters of the Chartres cathedral can be explained nearly entirety 98%, by the Isis star declinations. The probability of this celestial configuration not being a random result or something left up to fate by the designer of Chartres is F=0.9999997. This correlation was not happening in one single day, but occurred every day during the first 32 years of construction of the Catedral, due to the own stars movement and the axial precession movement of the earth. The second main result can be stated as: The center of the Labyrinth and the Rose window of the main facade of the Chartres catedral were lined up with the central star Elthor from the Tauro constellation, which is an Isis=Notre-Dame catasterismi. This alignement occurred with total accuracy and the whole constellation covered, on its daily trajectory, completely the Labyrinth.
