Foreword by the astronomer Xenophon Mousas , Emeritus Professor of the University of Athens.

Reading the work of Cleomidos one will marvel at the various scientific truths formulated 2000 years before us. The "Cyclic Theory of Meteors" is an original treatise that touches on issues of astronomy, astrophysics, celestial mechanics, geodesy, geography, physics and even philosophy. But it is a "dense" work, a work that requires careful in-depth study because all the opinions it contains are formulated in a rhetorical and synoptic manner. The researcher encounters "disgusting thoughts" in this book. Thoughts that were repeated many centuries later by later philosophers and astronomers.
