Commissioned for Umbigo magazine dialogues project, André Sier developed an unique set of photographs with drawings published in Umbigo #68 entitled 'Ant i Purga (Es7#agos da F0rmiga Br4nca)'.
The series of drawing-photographs juxtaposes ant lairs in books within the Torre do Tombo national archive with drawings performed from data obtained by a human purga at a library from 1929. José Pardal Pina wrote a text for the project, and you can find the text and images at continuum's text area.
