Image result for what is the golden ratio in art
Most often we call it the Golden Section, Golden Ratio, or Golden Mean, but it's also occasionally referred to as the Golden Number, Divine Proportion, Golden Proportion, Fibonacci Number, and Phi. You'll usually find the golden ratio depicted as a single large rectangle formed by a square and another rectangle.
Answer:
Raphael’s Madonna of the Meadow depicts the Virgin Mary with Jesus Christ the child and John the Baptist. Mary is the largest figure, anchoring the foreground in stable triangular form. The deep hues of her blue cloak and red dress emphasize the triangle, and force the baby Christ and John the Baptist further into the foreground. The baseline of the triangle is created by Mary’s cloak; John marks the left corner, Jesus is at the center, and Mary’s foot (highlighted to compensate for its small size) marks the right corner. Raphael contrasts earthy tones and deeper shades in the middle and foreground against the pale, bluish background to create a square. The combination square and triangle, both Renaissance symbols of the perfection of Nature, provide stasis and unity. Each shape draws the viewer’s eye: The triangle directs attention to Mary’s face, the square (from Mary’s chest to the bottom of the painting) directs the viewer to the figures of Jesus and John. Raphael creates depth in the middle ground by showing small trees. In the background, he uses atmospheric perspective to create depth: the pale shades, blue tint, and smudged lines of the hills and village across the lake. Each figure casts a shadow on the ground, and shadowing between Mary and Jesus creates space between them to create volume.
