'Magnetism II' 2012 In the series Magnetism, what at first appear to be pilgrims circling the Ka’ba, the sacred building at the heart of the sanctuary at Mecca, are in fact iron filings spiralling around a cube-shaped magnet. Mater refers to the spiritual force that Muslim believers feel during Hajj, the pilgrimage to Mecca. By creating photographs that recall well-known images on a dramatically different scale, Mater also questions the reliability of photography.
