How the oldest science in the world flourished in Toledo 1,000 years ago
15 May 2025, 18:15 Almost 2,000 years ago, in Africa, specifically in the city of Alexandria in Egypt, Claudius Ptolemy wrote a set of 13 books known as Mathematical Syntax. This Ptolemaic treatise summarized the most widely accepted concept of the universe throughout most of history, only replaced a little over 500 years ago, after the Copernican revolution.
