There is a legend that a Jewish king once reigned in Poland. It never occurs to my mind without at the same time conjuring before me two figures. The one is that charming creation of Ghetto fancy, old Malkoh "with the stout heart," in Aaron Bernstein's _Mendel Gibbor_, who introduces herself with the proud boast: _Wir sennen von königlichein Geblüt_ ("We are of royal descent"). The other is a less ideal, less attractive Jew, whom I overheard in the Casimir, the Jewish quarter at Cracow, in altercation with another Jew. The matter seemed of vital interest to the disputants. The one affirmed, the other denied as vigorously, and finally silenced his opponent with the contemptuous argument: "Well, and if it comes about, it will last just as long as Saul Wahl's _Malchus_ (reign)." Legend has always been the companion of history. For each age it creates a typical figure, in which are fixed, for the information of future times, the fleeting, subtle emotions as well as the permanent effects produced by historical events, and this constitutes the value of legendary lore in tracing the development and characteristics of a people. At the same time its magic charms connect the links in the chain of generations. The legend about Saul Wahl to be known and appreciated must first be told as it exists, then traced through its successive stages, its historical kernel disentangled from the accretions of legend-makers, Saul, the man of flesh and blood discovered, and the ethical lessons it has to teach derived.
