On the whole, it may be said that in the Middle Ages the journey to Palestine was fraught with so much danger that it was gallantry that induced men to go mostly without their wives. And, generally speaking, the Jew going abroad to earn a living for his family, could not dream of allowing his wife to share the dangers and fatigues of the way. In Ellul, 1146, Rabbi Simeon the Pious returned from England, where he had lived many years, and betook himself to Cologne, thence to take ship home to Trier. On the way, near Cologne, he was slain by Crusaders, because he refused baptism. The Jewish community of Cologne bought the body from the citizens, and buried it in the Jewish cemetery. No doubt it was often a cruel necessity that separated husband and wife. The Jewish law, even in lands where monogamy was not legally enforced, did not allow the Jew, however, to console himself with one wife at home and another abroad. Josephus, we know, had one wife in Tiberias and another in Alexandria, and the same thing is told us of royal officers in the Roman period; but the Talmudic legislation absolutely forbids such license, even though it did not formally prohibit a man from having more than one wife at home. We hear occasionally of the wife's growing restive in her husband's absence and taking another husband. In 1272, Isaac of Erfurt went on a trading journey, and though he was only gone from March 9, 1271, to July, 1272, he found, on his return, that his wife had wearied of waiting for him. Such incidents on the side of the wife were very rare; the number of cases in which wife-desertion occurred was larger. In her husband's absence, the wife's lot, at best, was not happy. "Come back," wrote one wife, "or send me a divorce." "Nay," replied the husband, "I can do neither. I have not yet made enough provision for us, so I cannot return. And, before Heaven, I love you, so I cannot divorce you." The Rabbi advised that he should give her a conditional divorce, a kindly device, which provided that, in case the husband remained away beyond a fixed date, the wife was free to make other matrimonial arrangements. The Rabbis held that travelling diminishes family life, property, and reputation. Move from house to house, and you lose a shirt; go from place to place, and you lose a life--so ran the Rabbinic proverb. This subject might be enlarged upon, but enough has been said to show that this breaking up of the family life was one of the worst effects of the Jewish travels of the Middle Ages, and even more recent times.
