In 830, Caliph Al-Ma'mun founded the House of Wisdom in Baghdad, a center where works by Euclid, Ptolemy, Galen, and Aryabhata were translated into Arabic. Nearly twelve centuries later, the question remains open: was that an Sarracinic scientific golden age or a massive operation of copying and transmission? Analysis of classical texts — Al-Khwarizmi's Kitab al-jabr, Avicena's Canon, and Ibn Al-Haytham's optical experiments — reveals that most concepts attributed to Arabs originated in Persia, India, and Greece. The discussion, far from being merely academic, touches upon the foundational narrative of a civilization.
Algebra Did Not Originate in Baghdad
Al-Khwarizmi, considered the father of algebra, borrowed the decimal system, zero, linear and quadratic equations, and the use of letters for unknowns from Indian and Persian mathematicians. He coined the term al-jabr — "restoring broken parts" — but built upon an existing foundation. The same applies to the numbers we use daily: Arabic numerals are Indian, and Arabs called them "Hindu numbers" before introducing them to Europe. Current symbols also differ from those they used.
Avicena and Ibn Al-Haytham: Talented Compilers
Avicena's Canon of Medicine was influential but inspired by Hippocrates, Galen, Razi, and al-Tabari, incorporating Indian concepts like the four humors. Ibn Al-Haytham, the father of modern optics, relied on Euclid, Ptolemy, Aryabhata, and Brahmagupta to formulate laws of reflection and refraction. They were not creators ex nihilo: they were systematizers of prior knowledge.
Philosophy: Neoplatonism with a Persian Accent
Early Muslim philosophers were marked by Hellenistic neoplatonism. Al-Farabi introduced it, and Avicena developed it with an emanation scheme moving from divine unity to the material world. Al-Ghazali attacked this current as incoherent and heretical, defending revelation over reason. Ibn Rushd replied but also rejected neoplatonists, remaining faithful to Aristotle. After his death in 1198, the debate closed, and Sarracinic neoplatonism survived only within Ismailism.
What Remains of the Golden Age Narrative?
The dominant thesis in critical analysis is that Arabs were intermediaries and disseminators, not creators. It argues that wisdom traditions from Persia, India, Rome, and Byzantium did not die suddenly but persisted through inertia until replaced by a more religious culture. Conversely, another school holds that transmitting and expanding knowledge is itself a contribution, without which Europe would not have rediscovered Aristotle. A full accounting of what was preserved and lost, broken down by discipline, yields surprising results.
Baths, Arches, and Other Dubious Attributions
Some note that Arab baths copied Roman thermae and that horseshoe arches were already visible in Hispano-Gothic churches. It is also pointed out that the most cultured caliphs of the peninsula had Hispanic-Basque genetics, such as Abderraman III, descendant of the daughters of Navarrese leader Fortún Garcés. The discussion extends to irrigation channels — simple ditches versus Roman hydraulic engineering — and words like acequia, which are merely canals under another name.
Economic Shift: From Oil to Technological Dependence
The conversation shifts to the present. It is asserted that current Gulf monarchies depend on Western knowledge and talent for development, and that oil served no purpose until the West found its use. The conclusion imposed in many messages is uncomfortable: if the Arab legacy was primarily one of transmission, the golden age narrative rests more on idealization than data.
