Sir Isaac Newton did not have leisure to peruse this convex Artifact, however. He had been escorted to the library by young Johann von Hacklheber—a Leipziger baron. And so he was not extremely surprised to recognize a second North German baron—Gottfried Wilhelm von Leibniz—rising from a chair to bid him welcome. Newton’s face showed that he was annoyed to have been ensnared into yet another extraordinary and irregular meeting with his Nemesis, but that he would stiffen his upper lip and get through it. He glanced for only a moment at the young woman seated in an armchair near the globe. His eyes then snapped back to Leibniz. "I was led to believe I should be paying a call on the Duchess of Arcachon-Qwghlm," he began. But his protest trailed off as his eyes wandered back to behold the young woman. It was not just that she was good looking, though she more or less was. It was rather that she was turned out in clothing and jewels—especially, jewels—the likes of which Newton had not feasted his protruberant eyes on since the last time he had been summoned into the presence of Royalty. The woman was, in fact, wearing an actual tiara, and something in her bearing told Newton that it was no affectation, and that the sparkly bits were no rhinestones.
