Sphinx 

"Sphinx," a work by Czech artist Frantisek Kupka, is a monochromatic drawing featuring a solitary figure walking through a narrow, seemingly endless, street. The perspective is slightly distorted, as if the walls of the street are closing in on the figure, adding a sense of unease. The overall effect is one of isolation and mystery, reminiscent of the enigmatic nature of the Sphinx itself. The use of stippling and shading creates a sense of depth and texture, further enhancing the haunting atmosphere of the piece.
