Which of the following did author Khalil Gibran not write?

Gibran Khalil Gibran, usually referred to in English as Kahlil Gibran was a Lebanese-American writer, poet, and visual artist, also considered a philosopher although he himself rejected the title. He is best known as the author of "The Prophet", which was first published in the United States in 1923 and has since become one of the best-selling books of all time, having been translated into more than 100 languages. Born in a village of the Ottoman-ruled Mount Lebanon Mutasarrifate to a Maronite family, the young Gibran immigrated with his mother and siblings to the United States in 1895. In 1904, Gibran's drawings were displayed for the first time at Day's studio in Boston, and his first book in Arabic was published in 1905 in New York City.

In 1911, Gibran settled in New York, where his first book in English, "The Madman", would be published by Alfred A. Knopf in 1918 with the writing of "The Prophet" or "The Earth Gods" also underway. By the time of his death at the age of 48 from cirrhosis and incipient tuberculosis in one lung, he had achieved literary fame on "both sides of the Atlantic Ocean," and "The Prophet" had already been translated into German and French. His body was transferred to his birth village of Bsharri (in present-day Lebanon), to which he had bequeathed all future royalties on his books, and where a museum dedicated to his works now stands.
