Not just oil is part of a series of landscape paintings intervened with tar, alluding to the spills caused by the petrochemical industry. The series began in 2007 when the artist intervened in a painting that portrayed the Popocatépetl volcano in reference to Ezequiel Ordoñez, the geologist who made commercial oil extraction possible in Mexico and who wrote historical accounts of the country’s orography. This intervention brings us face to face with a natural element on top of an idealized and unreal image.
