The construction of the Galerie des Glaces is a turning point in the Versalles1 history about the relation between Le Brunand architects, the palace's nature and the aesthetic of mirror. The issue of this paper is a iconographical change of its plafond andits influences on the relation between the chateau and the gardens. At first, Apollonian themes were projected, but they werereplaced by Herculean myth, finally, by the histoire du Roi. The first plan that connects with the gardens' subjects as the palaisdu Soleil's keystone was abandoned and the harmony of the composition wasn't achieved.
