*Metros* by Cildo Meireles consists of a series of painted wooden rulers that have been subtly altered, their standard units of measurement rendered unreliable through the artist's intervention. By tampering with these everyday instruments of precision, Meireles undermines the authority of official systems of measurement and the institutional power structures they represent. The work reflects the artist's broader conceptual practice of questioning normativity and exposing the constructed nature of the rules—both literal and societal—that govern daily life.
