said to have been the inventor of maps and charts. He was born about B.C. 610 That the earth is a plane, and that the heavens are a firmament (STEPEOs), or solid substance like the earth, maintained by Anaximenes, who is said to be the inventor of sun-dials (though probably only the introducer of them into Greece.) He was born about

That the ethereal, or upper regions of the atmosphere, were fire; that the fire drew up from the earth, and ignited, masses of stone, which thus became stars; that the comets were wandering stars; that the light of small stars occasioned the white color of the milky way, and that the moon is irregular in its surface, and habitable like the earth, maintained by Anaxagoras-a meteoric stone that fell in Thrace probably misled him as to the ethereal regions and the stars. His conjectures with regard to the milky way and the moon have been confirmed, as far as observations have been carried" The same philosopher was the first who wrote on the phases of the moon and eclipses.

He was born about B.C. Pythagoras, the disciple of Thales, travelled, like his master, into the east, and, like him, corrected the errors into which his countrymen had fallen. He demonstrated, from the varying altitudes of the stars by change of place, that the earth must be round; that there might be antipodes on the opposite part of the globe; that Venus was the morning and evening star; that the universe consisted of twelve spheres-the sphere of the earth. the sphere of the water, the sphere of the air, the sphere of fire, the spheres of the moon, the sun, Venus, Mercury, Mars, Jupiter, and Saturn, and the sphere of the stars. Fe admitted the idea of a plurality of worlds, and even calculated the height of the people in the moon; and he maintained that the motions of the twelve spheres must produce delightful sounds inaudible to mortal ears, which he called "the music of the spheres. He was persecuted, and is said to have
