In Marrow both the physical and the metaphysical are inhabited in the same figure. The transience and vanity of mortal life embodied in the decaying body of the Transi (cast from a 1545 tomb effigy at the Church of Saint Etienne in Bar-le-Duc), serves as a backdrop for, not-so-much the afterlife, but a parallel universe. Andersson has added a tesseract to the figure’s upstretched left hand. A tesseract, or a hypercube – is a mathematical object that can be described in simple terms as the geometric analogue of the square of a number: a squared cube. This is illuminated by a beam of light that projects the illustration of a ‘simple’ cube on the wall. In line with theories about n dimensions and their representation, with each object casting a shadow of itself in n-1 dimensions (a three-dimensional object always casting a two-dimensional shadow and a four-dimensional object would cast a shadow in three dimensions, etc.) the raised hypercube hence seems to make an appearance as a diminished maquette of a fourth dimension.

The projection goes from the mind to the image, leaving open the hypothesis that we do not accurately perceive the dimension in which we are living, that is, that we do not perceive the fourth dimension in which we exist and of which our three-dimensional image is only the projected shadow.
