Chapter XXIV.

Of the Eclipse of the Sun.

Thales was the first who affirmed that the eclipse of the sun was caused by the moon’s running in a perpendicular¹ line between it and the world; for the moon in its own nature is terrestrial. And by mirrors it is made perspicuous that, when the sun is eclipsed, the moon is in a direct line below it. Anaximander, that the sun is eclipsed when the fiery² mouth of it is stopped and hindered from respiration³. Heraclitus, that it is after the manner of the turning of a boat, when the concave seems uppermost to our sight, and the convex nethermost⁴. Xenophanes, that the sun is eclipsed when it is extinguished; and that a new sun is created and rises in the east. He gives a farther account of an eclipse of the sun which remained for a whole month, and again of an eclipse which changed the day into night. Some declare that the cause of an eclipse is the invisible concourse of condensed clouds which cover the orb⁵ of the sun. Aristarchus placeth the sun amongst the fixed⁶ stars, and believeth that the earth [the moon?] is moved about the sun, and that by its inclination⁷ and vergency it intercepts⁸ its light and shadows its orb. Xenophanes, that there are many suns and many moons, according as the earth is distinguished⁹ by climates, circles, and zones. At some certain times the orb of the sun, falling upon some part of the world which is untenanted, wanders in a vacuum and becomes eclipsed. The same person affirms that the sun proceeding¹⁰ in its motion in the infinite space, appears to us to move orbicularly, taking that representation from its infinite distance from us.
