Hans Holbein the Younger, The Ambassadors, 1533, is a clever depiction of perspective geometry. Holbein uses an important introduction of his learning and arithmetic to measure time via space. While you walk around the painting from one side to the other, the skull in the foreground gathers proportion to the real and the skull appears in the third dimension. This devise for the perspective of a pictorial plane is apparently occurred by flattening out perspective in a mirror, therefore, Holbein used a mirror to paint the skull. We observe all the instruments of men of learning on the shelf between the two ambassadors of his aid and these would do nothing other than describe the instruments Holbein would have used to equate God and understand the perspective of time. Holbein was equating God in the garden of Christ.
