ABSTRACT={The internal geometry allows painters to organize the pictorial space to make it coherent and harmonious. But the internal geometry and the support on which it is plotted, do not appear in the painted work, neither in its radiographic image, nor in its infra-red image: The internal geometry remains secret. However, since the support is sometimes a square meshing or most often a harmonic meshing, the pictorial elements are quantified, the internal geometry becomes "discrete" and can be detected at the same time as its support. The study presented here concerns the search for the internal geometry of one of Georges de la Tour&#8217;s masterpieces: "The Apparition of the Angel at Saint Joseph" (Museum of Fine Arts of Nantes). This study helps to illustrate and confirm the methodology developed in our book dedicated to internal geometry. It is also an invitation to read this book, which we will sometimes refer to.}}
