Cornelio Ghirardelli's "Cephalogia Fisonomica" is a 17th-century work that studies the features of the human face to deduce the character and inclinations of individuals. The work is divided into ten sections and contains drawings of one hundred human heads, accompanied by detailed descriptions and observations. Ghirardelli uses his knowledge of physiognomy, inspired by Aristotle and other natural philosophers, to analyze facial features and connect them to different character dispositions. Ghirardelli's work "Cephalogia Fisonomica" is an example of how physiognomy was considered a legitimate science in the 17th century. Ghirardelli, through a meticulous analysis of facial features, attempted to establish a connection between the shape of the face and the character of people.
