A great example of this is the painting The Flagellation of Christ by Piero della Francesca (1415-1492). It is a very good illustration of the Golden Rule (Rule of thirds): an image should be imagined as divided into nine equal parts by two equally spaced horizontal lines and two equally spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections. Proponents of the technique claim that aligning a subject with these points creates more tension, energy and interest in the composition than simply centering the subject. The Golden Rule was invented in Ancient Greece which shows that the painter was not only knowledgeable in Classical Culture but that he wanted to emulate it in his work and us its techniques. Additionally, the very lucid perspective of the painting which is quite realistic is also in rupture with the flatter medieval perspective that was the norm until then. Della Francesca's painting was considered scandalous in his time because the 3 dignitaries are not only much bigger than Christ being flogged but are also positioned in the foreground and occupy the main intersections of the golden ration rectangle. This was a breaking change of philosophy since giving human beings the most important compositional place within the frame expresses a humanist view. The Christ, who is much smaller and put on the background, symbolizes the reduced place of religion in society, a stark contrast with the ideology of the Middle Ages.

Answer:
Because it involves various stages and personnel and often does not get a bill passed.
Explanation:
The United States legislature was purposely designed to be slower in taking action. This is because the founding fathers wanted to prevent the infringement of citizens' rights and freedoms.
Thereby, the legislature involves various personnel and stages before bills and laws are passed. Also the legislature is bicameral in nature as it requires the passing of House and Senate through debates and votings.
The president who was most responsible for expanding the power of the presidency through the use of executive orders was Andrew Jackson. He dictated twelve executive orders, being the first American president to exceed ten executive orders during his term.
Executive orders are provisions issued by the President of the United States that administer the operations of the executive branch of the federal government.
Executive orders belong to administrative law, but have the force of law only when they are based on the executive powers granted directly to the President of the United States by the Constitution (Article II), or are dictated according to laws of Congress that explicitly delegate to the President a certain degree of discretionary power (delegated legislation).
