Question

how has the sculptor depicted this Egyptian pharaoh

Answer 1

Ancient Egyptian art refers to art produced in ancient Egypt between the 31st century BC and the 4th century AD. It includes paintings, sculptures, drawings on papyrus, faience, jewelry, ivories, architecture, and other art media. It is also very conservative: the art style changed very little over time. Much of the surviving art comes from tombs and monuments, giving more insight into the ancient Egyptian afterlife beliefs.

The ancient Egyptian language had no word for "art". Artworks served an essentially functional purpose that was bound with religion and ideology. To render a subject in art was to give it permanence. Hence, ancient Egyptian art portrayed an idealized, unrealistic view of the world. There was no significant tradition of individual artistic expression since art served a wider and cosmic purpose of maintaining order.
