Two faces of a staircase
The ascent is exhausting and arduous, in contrast the descent is easy and effortless. Just like the way up and down, a staircase visually presents itself from two sides.
The view from the bottom to the top reveals the lower surface of the flight of stairs, the handrail and the pattern of the ceiling on top. On the other hand the view from the top to the bottom brings up an entirely other image. You can see the pattern of the floor, the colour of the handrail and notice a different mood of light. Comparing the two angles of view, one time the same staircase presents itself completely different while another time the similar character is visible from both top and bottom.
