Michelangelo's  The last Supper uses one point perspective to direct us to the most important figure in the painting.

Actually, there seems to be a mix-up in your statement. It was Leonardo da Vinci, not Michelangelo, who painted "The Last Supper". The painting does indeed use one-point perspective to draw attention to the central figure, Jesus Christ. Here's how:

1. One-point perspective is a drawing method that shows how things appear to get smaller as they get further away, converging towards a single 'vanishing point' on the horizon line. It is a way of drawing objects upon a flat piece of paper (or other drawing surface) so that they look three-dimensional and realistic.

2. In "The Last Supper", da Vinci used one-point perspective with the vanishing point being Christ's head. This means all lines leading towards the horizon line converge at this point.

3. This technique draws the viewer's attention directly to Jesus, highlighting his importance in the scene. It also gives depth to the painting, making it appear more three-dimensional.

4. The use of perspective in this way was a relatively new technique during the Renaissance, and da Vinci was one of the pioneers of this method. His use of perspective in "The Last Supper" is considered one of the best examples of one-point perspective in the history of art.
