CHAPTER LI ---- OF AN ECLIPSE OF THE MOON.
'ANAXIMANDER: from the closing of the orifice of its circumference.
'Berossus: because of the turning of the dark side towards us.
'Heracleitus: because of the turning of the boat-like figure.
'Of the Pythagoreans some say that it is an outshining and obstruction by our Earth or the counter-earth: but the more recent say that it is in consequence of the spreading of a flame which is gradually kindled in an orderly manner, until it produces the complete full moon, and decreases again in like manner until the conjunction, at which it is entirely extinguished.
'Plato, Aristotle, the Stoics, and the Mathematicians agree that it effects its monthly obscurations by travelling round with the Sun and sharing its illumination; but the eclipses by falling into the shadow of the Earth when that comes between the two luminaries, or rather when it obstructs the light from the Moon.'
