THE MECHANICAL SCIENCES. (CONTINUED.)

HISTORY OF PHYSICAL ASTRONOMY.

DESCEND from heaven, Urania, by that name If rightly thou art called, whose voice divine Following, above the Olympian hill I soar, Above the flight of Pegasean wing. The meaning, not the name, I call, for thou Nor of the muses nine, nor on the top Of old Olympus dwell'st: but heavenly-born, Before the hills appeared, or fountain flowed, Thou with Eternal Wisdom didst converse, Wisdom, thy sister.

Paradise Lost, B. vii.
