The diagram illustrates two fundamental astronomical phenomena: eclipses in the upper half and the theory of the tides in the lower half. The English text explains that the water directly beneath the Moon is raised by its gravitational pull. As the Earth rotates on its axis once every 24 hours, every point on its surface experiences two high tides each day. When the Sun and Moon are in conjunction, this effect is amplified, resulting in what are known as spring tides. Historical school picture or wall hanging from around 1900, high-quality reproduction
