History of a World of Immortals without a God (1891)
“ Conspicuous above them all in beauty and brightness was the earth itself, which, being then in opposition, was at its least distance from the observers. When in that position, the earth presents to the Hesperians a much more brilliant object than their planet does to us. For, though not receiving as great a supply of light from the sun as Hesperos does, this deficiency is far more than balanced by the fact that, when in opposition, the whole of the illuminated face of the earth is visible at Hesperos, while only an exceedingly thin crescent of Hesperos is visible at the earth. ”
