caption: The image shows a drawing of a windmill in the middle of a river, surrounded by houses, trees, and a bridge. The drawing is on a piece of paper, and is believed to be from the 16th century. The windmill is a traditional Dutch design, with a tall tower and a winding windmill, and the river is a deep blue. The trees are lush and green, and there are a few birds flying in the sky. The bridge is a small wooden structure with a few people walking across it.
