Pierre Marie Lejeune was born in France in 1954. Pierre Marie Lejeune's works use two contrasting materials, mirrored stainless steel and glass, and most of his sculptures show geometric shapes similar to letters. He uses heavy materials such as iron, glass and steel to create works, and gives them simple, essential and eternal forms, abandoning anecdotes, decorative effects and useless detours. Therefore, he turned to imaginative letters and mysterious symbols. A horizontal bar is added to the letter O, sometimes the letter U is turned upside down or reversed, or the letter L is placed vertically or horizontally. These three extremely simple structural symbols are like the original form of human beings, and have nothing to do with Eastern and Western civilizations. These forms are eternal and extremely aesthetic.
