Foreword by Maro K. Papathanasiou , Emeritus Professor of the University of Athens.

The "Mathematical Syntax" of Claudius Ptolemy is one of the few intellectual creations of mankind, which have been so well-known over time and become well-known, that there is no need to even mention their creator. Along with Euclid 's "Elements", its only competitors were the holy books of the great religions, with a completely different content and purpose. (From the foreword of the book.)
