The Ecce Homo (Behold the Man) in the Sanctuary of Mercy church in Borja, Spain, is a fresco painted circa 1930 by the Spanish painter Elías García Martínez depicting Jesus crowned with thorns. Both the subject and style are typical of traditional Catholic art.
While press accounts agree that the original painting was artistically unremarkable, its fame derives from a good faith attempt to restore the fresco by Cecilia Giménez, an untrained elderly amateur, in 2012. The intervention reinterpreted the painting and made it look similar to a monkey, and for this reason it is sometimes known as Ecce Mono (Behold the Monkey).
