Preface

This book grew out of a dataset. The dataset, called Naql, records how fourteen classical books crossed languages: who translated each one, where, in which decade, for whom, and on what evidence. Every crossing in it names its carriers, cites published scholarship, and carries a grade. Attested means the medieval record itself names the act, or modern scholarship has settled it. Probable means the standard view stands on real but incomplete evidence. Disputed means the experts disagree.

A dataset can hold the facts. It cannot say what they amount to. That is what this book is for.

The argument is simple to state and surprisingly hard to hold onto. Ideas do not travel. They are carried, one decision at a time, by people who can be named, for reasons of their own, at prices someone agreed to pay. The history of thought is usually told in the passive voice and the language of weather: Greek science "flowed" into Arabic, learning "passed" to Europe, influence "spread" across the Mediterranean. Every one of those verbs is a small lie of omission. Behind each is a person sweating over a manuscript in a particular room in a particular decade, and usually an invoice.

Hold onto the names and the story changes shape. The grand currents dissolve into something much stranger and more human: a Persian physician memorizing a banned book, a patriarch ransacking a monastery library to fill a caliph's order, a Greek monk shipped to Spain because nobody in the caliphate of Cordoba could read a diplomatic gift, an Italian who learned Arabic for the sake of a single astronomy book and never came home. None of them was executing a plan. Together they moved the libraries of three civilizations.

The fourteen books behind these pages are not a sample in any statistical sense. They were chosen because their travels are documented well enough to meet the standard above, and because together they cover the great relay: Greek and Sanskrit into Syriac, Persian and Arabic; Arabic into Hebrew, Latin and Castilian; everything into print, and at last into English. The full chain of every book, with dates, places, carriers and citations, sits in the appendix. The bibliography lists every source the chains rest on. When the text says "probably," that word has been earned; when it reports a dispute, the dispute is real and the appendix says who stands where.

A note on method, in the same spirit of named carriers. This book was written by Adnan Abbasi with heavy use of AI, including the research: every chain was checked against published scholarship by independent verification passes before it entered the dataset, and the checking changed things. Dates widened. Attributions softened from fact to probable. One good story turned out to be an anachronism and was cut. The vagueness that remains is the accuracy. Errors that survive are the author's; the project's repository takes corrections, and corrections with citations outrank everything else.

One more word about the title. Naql is the Arabic term for carrying across: transport, conveyance, transmission. It is the word the ninth century used for translation itself, and a translator was a naqil, a carrier. English buried the same image inside its own word: translate comes from the Latin translatus, carried across. Two languages, a thousand years apart, agreeing on the same physical fact. A book does not move. Someone moves it.
