The Earth from Space, in 1660

Look downward on that globe, whose hither side
With light from hence, though but reflected, shines;
That place is Earth, the seat of Man; that light
His day, which else, as the other hemisphere,
Night would invade; but there the neighbouring moon
(So call that opposite fair star) her aid
Timely interposes, and her monthly round
Still ending, still renewing, through mid Heaven,
With borrowed light her countenance triform
Hence fills and empties to enlighten the Earth,
And in her pale dominion checks the night.
That spot, to which I point, is Paradise...
   -- John Milton, Paradise Lost III:722-733
