According to the legend, this is the night of Saul Wahl's brief royalty. It is said that he was an agent employed by Prince Radziwill, and when the electors could not be induced to come to an agreement, it occurred to the prince to propose Saul as a compromise-king. With shouts of "Long live King Saul!" the proposal was greeted by both factions, and this is the nucleus of the legend, which with remarkable tenacity has perpetuated itself down to our generation. For the historical truth of the episode we have three witnesses. The chief is Prince Nicholas Christopher of Radziwill, duke of Olyka and Nieswiesz, the son of the founder of this still flourishing line of princes. His father had left the Catholic church, and joined the Protestants, but he himself returned to Catholicism, and won fame by his pilgrimage to Jerusalem, described in both Polish and Latin in the work _Peregrinatio Hierosolymitana_. Besides, he offered 5000 ducats for the purchase of extant copies of the Protestant "Radziwill Bible," published by his father, intending to have them destroyed. On his return journey from the Holy Land he was attacked at Pescara by robbers, and at Ancona on a Palm Sunday, according to his own account, he found himself destitute of means. He applied to the papal governor, but his story met with incredulity. Then he appealed to a Jewish merchant, offering him, as a pawn, a gold box made of a piece of the holy cross obtained in Palestine, encircled with diamonds, and bearing on its top the _Agnus dei_. The Jew advanced one hundred crowns, which sufficed exactly to pay his lodging and attendants. Needy as before, he again turned to the Jew, who gave him another hundred crowns, this time without exacting a pledge, a glance at his papal passport having convinced him of the prince's identity.[73] This is Radziwill's account in his itinerary. As far as it goes, it bears striking similarity to the narrative of Rabbi Pinchas of Anspach, and leads to the certain conclusion that the legend rests upon an historical substratum. A critic has justly remarked that the most vivid fancy could not, one hundred and thirty-one years after their occurrence, invent, in Anspach, the tale of a Polish magnate's adventures in Italy. Again, it is highly improbable that Saul Wahl's great-grandson read Prince Radziwill's Latin book, detailing his experiences to his contemporaries.
