Astarte was much more beautiful than that Semira who had such a strong aversion to one-eyed men, or that other woman who had resolved to cut off her husband’s nose.  Her unreserved familiarity, her tender expressions, at which she began to blush; and her eyes, which, though she endeavored to divert them to other objects, were always fixed upon his, inspired Zadig with a passion that filled him with astonishment.  He struggled hard to get the better of it.  He called to his aid the precepts of philosophy, which had always stood him in stead; but from thence, though he could derive the light of knowledge, he could procure no remedy to cure the disorders of his lovesick heart.  Duty, gratitude, and violated majesty presented themselves to his mind as so many avenging gods.  He struggled; he conquered; but this victory, which he was obliged to purchase afresh every moment, cost him many sighs and tears.  He no longer dared to speak to the queen with that sweet and charming familiarity which had been so agreeable to them both.  His countenance was covered with a cloud.  His conversation was constrained and incoherent.  His eyes were fixed on the ground; and when, in spite of all his endeavors to the contrary, they encountered those of the queen, they found them bathed in tears and darting arrows of flame.  They seemed to say, We adore each other and yet are afraid to love; we both burn with a fire which we both condemn.

Zadig left the royal presence full of perplexity and despair, and having his heart oppressed with a burden which he was no longer able to bear.  In the violence of his perturbation he involuntarily betrayed the secret to his friend Cador, in the same manner as a man who, having long supported the fits of a cruel disease, discovered his pain by a cry extorted from him by a more severe fit and by the cold sweat that covers his brow.

“I have already discovered,” said Cador, “the sentiments which thou wouldst fain conceal from thyself.  The symptoms by which the passions show themselves are certain and infallible.  Judge, my dear Zadig, since I have read thy heart, whether the king will not discover something in it that may give him offense.  He has no other fault but that of being the most jealous man in the world.  Thou canst resist the violence of thy passion with greater fortitude than the queen because thou art a philosopher, and because thou art Zadig.  Astarte is a woman:  she suffers her eyes to speak with so much the more imprudence, as she does not as yet think herself guilty.  Conscious of her innocence she unhappily neglects those external appearances which are so necessary.  I shall tremble for her so long as she has nothing wherewithal to reproach herself.  Were ye both of one mind, ye might easily deceive the whole world.  A growing passion, which we endeavor to suppress, discovers itself in spite of all our efforts to the contrary; but love, when gratified, is easily concealed.”

Zadig trembled at the proposal of betraying the king, his benefactor; and never was he more faithful to his prince than when guilty of an involuntary crime against him.
