Once upon a time, there was a magical window in a forgotten castle. By looking through it, one could see different times and places, a feature that thrilled anyone who discovered it. The window, however, had a unique quality. It showed not just any time or place, but the evolution of windows themselves across human history. When you first peeked, you would see primitive huts with small holes serving as windows, providing ventilation and a glimpse of the outside world. As you continued to gaze, you'd see Roman times, where windows were covered with animal hide or thin slices of marble, followed by the Middle Ages with their glass windows, a luxury only the rich could afford. The journey continued through the Renaissance, showcasing windows with multiple panes, and later ones with sash, allowing them to be opened and closed. Today, we have windows of all shapes and sizes, playing vital roles in our lives. They let in light, provide ventilation, contribute to the energy efficiency of our homes, and offer us views of the world outside. Without windows, our homes and other buildings would be dark, stuffy, and isolated. From mere holes in the wall to beautifully designed fixtures, windows have a fascinating history. And they continue to evolve, reminding us that in architecture, as in life, there's always room for innovation and improvement.
