Fig. 2. Picture of the marble statue (a); layout of the future position (b). The work has started with a photogrammetic surveyof the statue, in order to detect the geometry of thestatue and the center of mass (Figure 3):

Given the future positionof thestatue, dependingon there-organizationof the Museum, theactual safe collocation problem is strongly influenced by the type of motion, as reported in the followingpicture, where it is shown that all the examined motion can lead to an impact of the statue on the back wa ll. As a first approximation the motion has been considered symmetric with respect to the centroid axis (Guadagnuolo et a l. 2019).
