Prudence at first refuses; but Concordia rises, the inspirer of chaste loves, she who knit the souls of David and Jonathan, Pirithous and Theseus, Nisus and Euryalus, Orestes and Pylades. Persuasively she speaks, and points out all the ills the world had suffered by disobedience to her behests. Prudence is won over to the task, and now wills only as her sisters will. She thinks upon the means and way. Wisdom orders a chariot to be made, in which the sea, the stars, the heavens may be traversed. Its artificers are her seven daughters, wise and fair, who unite the skill and knowledge of all those wise ancients who had excelled in any Art. First Grammar (her functions and great writers being told) forms the pole which goes before the axle-tree (_temo praeambulus axis_). Then Logic makes the axle-tree; and Rhetoric adorns the pole with gems and the axle with flowers. Arithmetic constructs one wheel of the chariot, and Music the second, Geometry the third, and the fourth wheel is made by Astronomy.[138] Now Reason, at Nature’s nod, yokes to the chariot the five horses, to wit, the Senses disciplined and controlled, Sight, Hearing, Smell, Taste, and Touch. He himself mounts as charioteer, and bids Prudence follow. Amid the farewells and plaudits of all, the chariot soars aloft. As it speeds along, Prudence investigates atmospheric phenomena, and then the spirits of evil who wander through the air. They passed on through the upper ether, reached the citadel and fount of light, where the Sun holds sway; next was reached the region where Venus and the star of Mercury sing together and Lucifer exults, the herald of the day. Then to their rapid flight appeared Mars’ flaming palace, seething with fire and wrath. Onward they passed to the glad light and unhurtful flames of Jupiter, and then to Saturn’s sphere. At length they ascended the stellar region where the Pole stars contend in brightness, where are seen Hercules and Orion, Leda’s twins, the fiery Crab, the Lion, and the rest of the Zodiac’s constellations.[139]
