This work, by Long Spring, a relatively new artist team consisting of artists Kim Jae-gak and Han Chang-gyu, sheds a new light on the fundamental problems of space as we perceive it. The concept of space that they propose is largely divided in two: the physical space where the sculptural work is positioned, and the psychological space of the viewer who perceives the spatial mass of the work. They devised a method called ‘Space Drawing’ to draw the planar ‘line’ in a three-dimensional space, and created a fourth dimensional space through the shape of horses using the cursive style font — one of the traditional fonts of East Asian calligraphy. Installed without a pedestal, this work rejects the authority of art and becomes a subject of play, opening communication channels between people. Also, through the visual experience of the empty spaces read in between the lines, with the ever-changing scenes of the ocean in the background, The Horse in Dream delivers different sensations according to each time and location.
