To draw the curtain on something

Origin

Imagine the hush of a packed 18th-century playhouse as the final scene of a grand drama unfolds. As the last lines are delivered and the applause begins, a stagehand grasps the ropes, and with a stately, deliberate motion, the heavy velvet curtains are drawn together, obscuring the stage from view. This definitive, physical act didn't just hide the set; it was the ultimate signal, the unequivocal declaration that the performance was over, the story told, the drama concluded. From this dramatic theatrical flourish, the phrase migrated into everyday language, perfectly capturing the sense of bringing any endeavor, an era, or even a life's work to a formal, final, and often ceremonial close, leaving the audience, or the world, to reflect on what has just transpired.
