A cinematic and evocative 4K portrait of an intense, observant man in his late 60s from the early 17th century, standing near an open arched window at night. He features a distinctive high, wide, and prominent receding forehead, with his hair receding deeply at the temples. His face is remarkably wide and full, characterized by prominent, fleshy, and rounded cheeks that catch the light, completely free of any hollows or gaunt shadows. His facial structure is stocky and jovial, with a thick, soft double chin partly visible beneath his dense, compact gray-and-white beard. His sharp, analytical dark eyes look intently upward toward a starry night sky. A well-defined gray-and-white mustache covers his upper lip, merging into a thick, squared beard that frames his heavy, rounded jawline. He wears a simple, heavy dark woolen doublet with a modest white collar. In his hands, he holds a long, slender, primitive telescope made of a dark wood cylinder. A faint, warm candlelight from inside the room illuminates his wide face, highlighting the smooth, full volume of his rounded cheeks and his high forehead. Photorealistic, dramatic chiaroscuro lighting, oil painting texture.
