Masa
The word “masa” in Spanish is the same as “mass”. With this metaphor in mind, I placed corn dough in the floor and covered it with a thin plastic sheet for people to walk over it and leave their footprints.
After the footprints were inscribed in the tortilla dough, I took off the plastic sheet and let the dough dry. This photograph shows how the footprints looked as the dough was drying and cracking.
