The work of Aristarchus of Samos On the Sizes and Distances of the Sun and Moon is one of the few works of Ancient Greek Mathematicians - Astronomers that have survived. It represents one of the first monuments of the application of mathematics to scientific study.

As the reader will discover, the language of the treatise is similar to that of the Elements of Euclid, and it follows the well-known terminology of Ancient Greek Mathematics.

The undersigned feels particularly proud, as after approximately 2,280 years, this wonderful treatise of Aristarchus is being reissued in a complete form.
