Unlike Kcho’s rusty machetes, which recall Cuba’s history but pose only a metaphorical threat, the sharpened steel knife-steps in Marina Abramovic’s 1996 installation “Double Edge” (V1, p. 126–127) can cause real physical harm. Here, as in much of her work, Abramovic examines the limits of physicality, provoking in the viewer an emotional involvement on the level of reflex. The work consists of four ladders with rungs made of different materials – from ordinary smooth wood to knife blades, heated metal and icy rails. The sight of these ladders whose familiar form has been transformed into something dangerous causes psychological discomfort in the viewer. These “dangerous steps” are a metaphor for trials that have to be overcome by overcoming mental and physical fears. In the museum setting, this installation did not involve physical contact, but in 2002, Abramovic revisited the ladders in her performance piece, “The House with the Ocean View” (V1, p. 124–125). For twelve days the artist lived in specially built minimalist rooms, open for viewing by visitors to the gallery. Under these conditions, ordinary actions take on the ritual character of a trial, a test combining asceticism and total publicity. Ladders with knives for rungs physically prevent the artist from going beyond the allotted space, thus an inanimate passive object becomes an actor in the performance, demonstrating its power over the will of the artist.

In another project, “The Abramovic Method” (2016), at the Benaki Museum in Athens, the viewer becomes part of the performance that takes place on a gently sloping ramp that connects floors of the museum on the way to the main exhibition space. The artist has deliberately chosen a space in the museum that is usually considered secondary, to be passed through quickly. Participants in the performance are forced to move in slow motion, concentrating on a more profound consciousness of their bodies in time and space; this is particularly noticeable in contrast to the movement of other visitors to the museum. In this way, Abramovic induces the viewers to focus, through body experience, on a specific “episode” of life.

Artists began to portray movement on stairs in painting at the end of the 19^>thcentury. Marcel Duchamp’s famous 1912 cubist painting, “Nude Descending a Staircase” (V1, p. 183), which The New York Times christened “Explosion at the Tile Factory”, depicts a woman’s motion down five steps along a spiral staircase through the successive overlapping of individual fragments. The painting was inspired by the new technology of cinema and particularly by Eadweard Muybridge’s famous series of photographs “Woman Descending Stairs”, made in 1887.

Gerhard Richter’s “Ema. Nude on a Staircase” (V1, p. 185), painted in 1966 is a comment on Duchamp’s work. Like Duchamp, Richter based his painting on a photograph. The model was the artist’s wife, descending an ordinary staircase devoid of details that would indicate a particular time. Richter’s almost ghostly image, seemingly woven of dreams and memories, renders Duchamp’s experiment to the limits of traditional portrait painting, a genre much out of favor in the art world of the 1960s. Richter’s painting later served as an inspiration for Bernhard Schlink’s 2014 novel, “The Woman on the Stairs”.
