Unknown path consists of portraits of unknown people photographed on the streets a few years ago, unaware that they were being photographed. Each portrait was created by a continuous line, and all were stitched together at the eye level, proposing a threshold between the known and the unknown - it is possible to imagine who these people are, but it is necessary to get closer to try to slip into their intimacies. The work was thought of as another form of symbolic touch: bodies that cross the same paths that can leave marks on each other.
