He continued to lie in place, still breathing heavily. I tried to keep myself calm. Then, with a sigh, he said, "I have need of a certain stone that I once possessed. It would allow me to leave this bed, despite my current illness. My problem is that it was not made in this realm, but by a human, and only a human may handle it. The herb vendor will tell you where you can find it. If you would fetch me this stone, I would tell you what I can." "Of course we will fetch you the stone," Nepthys assured him. "You have our thanks." Outside, the thing at the herb cart nodded when we mentioned the stone. He told Nepthys the name of a woman who lived on a certain street, and we set off. When we reached the street, I expected some sort of temple, or a row of antiquaries, or at least a sleazy, black-market relics merchant. Instead, it looked like we were in the red-light district: women who probably wanted more than our money eyed us from the alleys. Nepthys didn't need to warn me not to speak to them. He took us to the door of a building like a short pagoda that had a sign hanging over it showing a face with hands uplifted, like a saint under G d's light, and handcuffed. Inside, the entrance room was hung with bright silks and scattered with velvet cushions. Sails of obscene orange and a green that insulted springtime hung draped across reds that might have been sensual elsewhere but here were only offensive. A large woman, similarly decorated, quickly drifted up to us. "Good evening, gentlemen," she said. "May I invite you to have a cup of tea?" "No, thank you," said Nepthys, "we regret that we cannot take up your kind offer. Are you the proprietor of this shop?" "Yes," answered the woman. "I am Madame Entera, at your service. <sep>Who can tell me where to find the stone?<sep>The Herb Vendor

Einstein and Maric married in January 1903. In May 1904, the couple's first son, Hans Albert Einstein, was born in Bern, Switzerland. Their second son, Eduard, was born in Zurich in July 1910. In 1914, the couple separated; Einstein moved to Berlin and his wife remained in Zurich with their sons. They divorced on 14 February 1919, having lived apart for five years. Eduard, whom his father called "Tete" (for petit), had a breakdown at about age 20 and was diagnosed with schizophrenia. His mother cared for him and he was also committed to asylums for several periods, including full-time after her death. The marriage with Maric does not seem to have been very happy. In letters revealed in 2015, Einstein wrote to his early love, Marie Winteler, about his marriage and his still strong feelings for Marie. In 1910 he wrote to her that "I think of you in heartfelt love every spare minute and am so unhappy as only a man can be" while his wife was pregnant with their second child. Einstein spoke about a "misguided love" and a "missed life" regarding his love for Marie. Einstein married Elsa Lowenthal on 2 June 1919, after having had a relationship with her since 1912. She was a first cousin maternally and a second cousin paternally. In 1933, they emigrated to the United States. In 1935, Elsa Einstein was diagnosed with heart and kidney problems; she died in December 1936. <sep>How much time passed, after Albert Einstein's father divorced his mother, that he re-married?<sep>About four months had passed
