This anthropology research comes from the alimentary interest towards the petrifaction of bread. The metaphorical relationship with "geophagia"(eat earth) is the synthesis between the morphological characteristics of the food and my material intervention that bases its roots in the dough. The Greek word “Kissa” indicates the bird pica and the food desire that women have during pregnancy. The medical language uses this bird to stigmatize this “deviant” behavior. During the late 1800s, psychiatry and colonialism look denounce this behavior because “perturbing”. Browsing the first part of the visual research you will find different types of paper and transparencies, that generate a poetic and, at the same time, a political imaginary. Instead, the second part of the research is composed of still life sculptures, made by the petrification process of the bread.
