“These carpets,” Settimio was saying, “are from the Caspian shores near Tabriz. The tapestries on the far wall were conceived by the magicians of Shiraz on the Persian Gulf and woven with the lost Kashan art of Infinite Knots that makes it impossible for even the restorers from the Vatican Museums to decipher where the rug begins and where the rug ends.”
“Cor,” Malory said, sitting down because his legs were finding it less easy than his brain to keep up with Settimio’s tour.
“The bolsters cushioning the walls are from Yemen, the censers from Kazakhstan. And the throne you are sitting on …”
“Sorry!” Malory jumped up.
“It is yours, mio Principe, the throne for the King of Septimania. Please …” Settimio took Malory’s elbow lightly and eased him back down. “This throne was carved by a single axe from a single apple tree in the garden of a palace in Baghdad. It was transported to Rome in person by the Caliph Haroun al Rashid as a belated wedding present for Gan and his bride Aldana, the red-haired daughter of Charlemagne, on the occasion of Charlemagne’s coronation as Holy Roman Emperor in the Year 800.”
“Not a bedtime story,” Malory said, rubbing his left palm along the armrest.
“No,” Settimio acknowledged. “Applewood. One tree.”
“But,” Malory said, standing up, the scientist in him awakening, “how do you know all this? How do you know it’s not just another story cooked up by some younger Scheherazade?”
“Books, mio Principe. I believe in books.” Settimio smiled, perhaps the first time Malory had seen him smile. “I believe you also know something about books. Would you be so good as to follow me?” Settimio walked to the far end of the majlis, where the niche in the eastern wall curved back between the Catholic vestibule and the Jewish dining room. Malory approached and looked inside.
“In here?” Malory asked. There was a passageway. A passageway of tile and wood and light — a light that led up, that led down, that led sideways. They walked. They walked some more. The rooms of the villa that Malory had seen felt like they must be mere anterooms, and yet Malory continued to follow Settimio through the passageway up to a wooden door padded in leather.
“The Sanctum Sanctorum,” Settimio said. “The true wealth of Septimania. The Holy of Holies.”
The padded leather gave only a hint of how discreetly Septimania veiled its treasure. Settimio opened the door and led Malory into the first room. It was equally modest — a low-ceilinged study, bare except for a seven-sided desk lit by a concentric fixture suspended from a coffered ceiling. The seven books on the seven sides of the desk were anything but simple.
“On the left,” Settimio said, pointing to one of seven boxes, “is the oldest manuscript in your collection — a Septuagint, dating from the third century BC, the Greek translation by seventy-two rabbis of the forty-six books of the Tanach, what the pope, as you may know, calls the Old Testament. Next to it is a Codex, complete with the New Testament, or at least many of the books of the Codex are still associated with the New Testament. It was commissioned by the Emperor Constantine shortly after his conversion to Christianity and given by Pope Leo III to Charlemagne in the year 800 on the event of his own coronation as Holy Roman Emperor. It is known as the Codex Septimania, although known as such to very few. Next is the first of the five Korans made around 650 AD by the Third Caliph Uthman, son-in-law of the Prophet Mohammed, the oldest Koran in existence, except, according to believers, for the Koran that was made by Mohammed the Prophet and which the Angel Gibreel keeps in his own Sanctum Sanctorum up in Heaven. The following two boxes hold the writings of Buddha in one, the Vedas of the Hindus in the other, including a fragment of the Rigveda that is thought to be over three thousand years old.”
A choked gurgle came from Malory’s throat. He was pleased that he was even that articulate.
“The sixth box, at your grandmother’s request, is the oldest version of Isaac Newton’s Principia Mathematica.”
“Wait a minute,” Malory said, suddenly waking up in a world he knew. “I’ve seen the oldest edition — Newton’s own copy of 1686. It’s back at Trinity College, in the Wren Library, with Newton’s handwritten corrections for the second edition.”
“You may find,” Settimio said, with a smile of some satisfaction, “that this copy predates the Trinity copy by some twenty years.”
“Twenty years!” Malory was shocked and then alarmed and then shocked again, like some ten-year-old junior scientist not quite convinced that sticking a fork into an electrical socket is a bad thing. “The manuscript?” he asked somewhat more stupidly, although just saying the words tickled his neck. “You have the original manuscript? From 1666? In Newton’s hand?”
“You have the manuscript,” Settimio corrected him. “This is all yours, mio Principe.”
“And the seventh book? The final book?”
“Is a box,” Settimio said, and waited for some type of reaction.
“Empty?” Malory asked.
“Open it and see.”
“But if I open it …” And Malory was back in the organ loft of St. George’s, Whistler Abbey, with Schrödinger’s cat and Louiza’s Pip and his own indecision.
“Simplex sigillum veri,” Settimio said.
“Simplex sigillum veri?”
“The simple is the sign of the truth.”
“Yes, yes,” Malory said, surprising himself that he had developed the haphazard annoyance of someone with servants. “I know what it means. I just don’t know what it means in this case.”
“Neither do I, my lord,” Settimio said mournfully. “But my instructions are to reply in such a manner. Should the new King of Septimania ask me whether the box is empty, my instructions are to reply Simplex sigillum veri.”
“Your instructions?” Malory asked. “Instructions from whom?”
“From my father,” Settimio answered, “who trained me the way his father trained him.”
“May I ask,” Malory ventured, a little more calmly, “whether previous kings of Septimania have asked the same question?”
“I have direct knowledge,” Settimio said, “of only one prior king, your great-grandfather. The father of your mother’s mother, the most recent king of Septimania.”
“So this is the first time you’ve had to say Simplex sigillum veri?”
“The first time, my lord, in my knowledge, that any of us Settimios have had to say it. Opening boxes used to be somewhat simpler.”
Malory sat at the desk. He rubbed the back of his scalp against the back of the tapestried armchair, as he had rubbed it so often against the crumbling foam of the Trinity College Senior Common Room sofa. So many things used to be somewhat simpler. Write, they had said back in Cambridge. The simple is the sign of the truth. They had known, all the other kings of Septimania had known what was in the box, or at least hadn’t doubted that there was something, one thing in the box. But for him, the first Quantum King of Septimania, the first one in love with a quantum woman whose position he might know or direction he might know but never the same at once, nothing was simplex. And the Truth?
