An epitome of astronomy, with the new discoveries including an account of the eídouraníon, or transparent orrery

A hands‑on guide to the heavens, this work walks listeners through a spectacular 20‑foot transparent orrery that brings the motions of the Sun, Earth, Moon and planets to life. By isolating each celestial body in turn, the narration shows how day turns into night, why seasons shift, and how the tilt of our planet creates alternating climates, all while the glittering zodiac signs frame the scene. Simple language and vivid visual cues make the underlying mechanics of eclipses, phases and orbital paths easy to grasp, even for those new to astronomy.

The second part expands the demonstration to include the Moon’s changing face and the dance of shadows that produces solar and lunar eclipses. Viewers can watch a miniature Earth rotate on its axis, see its shadow sweep across space, and follow the Moon’s 29‑day cycle of illumination. The clear, step‑by‑step explanations turn abstract concepts into tangible, memorable moments, inviting anyone who listens to feel the wonder of the sky’s grand clockwork.
