Q: Passage: Ancient historians, as well as modern ones, have also written on Alexander's marriage to Roxana the beautiful [Persian]n woman. Robin Lane Fox writes, "Roxana was said by contemporaries to be the most beautiful lady in all Asia. She deserved her name of Roshanak, meaning 'little star', (probably rokhshana or roshana which means light and illuminating) in Persian. Marriage to a local noble's family made sound political sense, but contemporaries implied that Alexander, aged 28, also lost his heart. A wedding-feast for the two of them was arranged high on one of the Persian rocks. Alexander and his bride shared a loaf of bread, a custom still observed in Turkestan. Characteristically, Alexander sliced it with his sword. Ulrich Wilcken writes, "The fairest prize that fell to him was Roxana, the daughter of Oxyartes, in the first bloom of youth, and in the judgment of Alexander's companions, next to Stateira the wife of Darius, the most beautiful woman that they had seen in Asia. Alexander fell passionately in love with her and determined to raise her to the position of his consort."
