Instructed in the sciences of the ancient Chaldeans, he understood the principles of natural philosophy, such as they were then supposed to be; and knew as much of metaphysics as hath ever been known in any age, that is, little or nothing at all.  He was firmly persuaded, notwithstanding the new philosophy of the times, that the year consisted of three hundred and sixty-five days and six hours, and that the sun was in the center of the world.  But when the principal magi told him, with a haughty and contemptuous air, that his sentiments were of a dangerous tendency, and that it was to be an enemy to the state to believe that the sun revolved round its own axis, and that the year had twelve months, he held his tongue with great modesty and meekness.

Possessed as he was of great riches, and consequently of many friends, blessed with a good constitution, a handsome figure, a mind just and moderate, and a heart noble and sincere, he fondly imagined that he might easily be happy.  He was going to be married to Semira, who, in point of beauty, birth, and fortune, was the first match in Babylon.  He had a real and virtuous affection for this lady, and she loved him with the most passionate fondness.

The happy moment was almost arrived that was to unite them forever in the bands of wedlock, when happening to take a walk together toward one of the gates of Babylon, under the palm trees that adorn the banks of the Euphrates, they saw some men approaching, armed with sabers and arrows.  These were the attendants of young Orcan, the minister’s nephew, whom his uncle’s creatures had flattered into an opinion that he might do everything with impunity.  He had none of the graces nor virtues of Zadig; but thinking himself a much more accomplished man, he was enraged to find that the other was preferred before him.  This jealousy, which was merely the effect of his vanity, made him imagine that he was desperately in love with Semira; and accordingly he resolved to carry her off.  The ravishers seized her; in the violence of the outrage they wounded her, and made the blood flow from a person, the sight of which would have softened the tigers of Mount Imaus.  She pierced the heavens with her complaints.  She cried out, “My dear husband! they tear me from the man I adore.”  Regardless of her own danger, she was only concerned for the fate of her dear Zadig, who, in the meantime, defended himself with all the strength that courage and love could inspire.  Assisted only by two slaves, he put the ravishers to flight and carried home Semira, insensible and bloody as she was.

On opening her eyes and beholding her deliverer, “O Zadig!” said she, “I loved thee formerly as my intended husband; I now love thee as the preserver of my honor and my life.”  Never was heart more deeply affected than that of Semira.  Never did a more charming mouth express more moving sentiments, in those glowing words inspired by a sense of the greatest of all favors, and by the most tender transports of a lawful passion.
