Marcel Duchamp implying that the woman in the painting is in a state of sexual excitement and availability. It may also have been intended as a Freudian joke, referring to Leonardo da Vinci's alleged homosexuality. Duchamp gave a "loose" translation of L.H.O.O.Q. as "there is fire down below" in a late interview with Arturo Schwarz. According to Rhonda Roland Shearer, the apparent "Mona Lisa" reproduction is in fact a copy modeled partly on Duchamp's own face. Research published by Shearer also speculates that Duchamp himself may have created some of the objects which he claimed to be "found objects". Duchamp worked on
Fountain (Duchamp) porcelain, with a signature reproduced in black paint. Of all the artworks in this series of readymades, "Fountain" is perhaps the best known because the symbolic meaning of the toilet takes the conceptual challenge posed by the readymades to their most visceral extreme. Similarly, philosopher Stephen Hicks argued that Duchamp, who was quite familiar with the history of European art, was obviously making a provocative statement with "Fountain": Since the photograph taken by Stieglitz is the only image of the original sculpture, there are some interpretations of "Fountain" by looking not only at reproductions but this particular photograph.
