Základní kurz na většině středověkých univerzit se skládal ze studia sedmi svobodných umění. Nižší úroveň (gramatika, rétorika a dialektika) se nazývala trivium a úroveň vyšší, kvadrivium, zahrnovala studium aritmetiky, geometrie, hudby a astronomie. Kvadrivium lze chápat jako studium čísel ve vztahu k prostoročasu: aritmetika se zabývá čistými čísly, geometrie čísly v prostoru, hudba čísly v čase a astronomie (kosmologie) čísly v časoprostoru. Kniha Kvadrivium vznikla jako syntéza šesti publikací řady Pergamen, která pro českého čtenáře již téměř deset let systematicky mapuje lidské poznání na pomezí vědy a tajemna. Stejně jako u jednotlivých titulů řady jde o atraktivně graficky zpracované ochutnávky velkých témat, které se nebrání mystice ani čisté spekulaci. Jednotlivé knihy byly pro Kvadrivium aktualizovány, doplněny o řadu nových kapitol, tabulek a přehledů a propojeny odkazovým aparátem. Kniha poskytne mnoho potěšení každému, kdo se nebojí přemýšlet o velkých tématech, a uvítá názorného průvodce po jejich říši s doprovodem stovek půvabných ilustrací.

Ve druhém dílu fantasy ságy se Jednomyslně zvolení setkají se zlem v nové podobě, ale je to hlavně Samuel, který mu bude čelit tváří v tvář. Přešel času běh a draci zmizeli. Zdálo by se, že zlo je poraženo a Jednomyslně zvolení bez překážek dostojí svému slibu. S jakou lehkostí by se tomu dalo uvěřit. Jenže pravda je jiná a odhaluje bezduché násilí, které tu po dracích zůstalo a z jehož temné hlubiny se vynoří hrůzovláda netušené síly. Ale prozatím není nic ztraceno a Poutník, Modrooká, Horal, Lovec a Johan jedou vstříc nové naději.

In the great battle which had returned control of Morvannec, the legendary city, to mankind, Elof the Smith had saved Kara, his love, from the immortal Power which ruled her. But in the seven years since, the Smith has grown fearful that Kara, herself no mortal, will one day leave him. In his fear, Elof makes the mistake of drawing on his own uncanny powers to bind Kara closer to him; he only succeeds in driving her away. Haunted, guilt-ridden, Elof can do nothing but follow his love eastwards, across the Seas of Sunrise, towards the city of Kerys in which Kermovan of Kerbryhaine's people had originated. In the myth-filled lands of the East, where the Powers of the Ice contemplate the total extinction of life, Elof must face his past, his future and his final destiny.

Golan Trevize, former Councilman of the First Foundation, has chosen the future, and it is Gaia. A superorganism, Gaia is a holistic planet with a common consciousness so intensely united that every dewdrop, every pebble, every being, can speak for all—and feel for all. It is a realm in which privacy is not only undesirable, it is incomprehensible. But is it the right choice for the destiny of mankind? While Trevize feels it is, that is not enough. He must know. Trevize believes the answer lies at the site of humanity's roots: fabled Earth . . . if it still exists. For no one is sure where the planet of Gaia's first settlers is to be found in the immense wilderness of the Galaxy. Nor can anyone explain why no record of Earth has been preserved, no mention of it made anywhere in Gaia's vast world-memory. It is an enigma Trevize is determined to resolve, and a quest he is determined to undertake, at any cost.[ Original description here: Горстка смельчаков пытается найти прародину человечества - Землю, чтобы получить разгадку тайн истории Галактики. = A handful of brave souls trying to find humanity's ancestral home—the Earth, to get answers to the mysteries of the history of the Galaxy.]
