Claude Bragdon was an architect from Rochester; he built the New York Central station there in 1909 and was seriously interested in theosophy. In the book A Primer of Higher Space (1913) he tried to draw the fourth dimension. In Projective Ornament (1915) he proposed making ornament out of it: laying out projections of four-dimensional figures on a plane to get patterns for a new architecture.
In the pen drawings these patterns are already at work. Stars on the sofa cushions and on a wall panel, a grid on the columns, wrought-iron gates, and by a post stands a girl a third the height of the gate leaf.
