Louis XI arranged with one of his Dauphinese familiars to take the infidel into his chateau. The alien was at first enchanted with his new life and played the zither and sang songs to the fair ladies of Dauphiny all the long day with all the gallantry of a noble of France. He went further: he would have married with one of the most gracious he had met: "It was a thing a thousand times more to be sought for than the control of the Ottoman Empire," he said. For the moment it was the one thing that the Turk desired in life. Proof goes further and states that for the purpose he became converted to Christianity. And the rest? The fair lady of Dauphiny did not marry the Turk; so he was sent a hundred leagues away in further exile and the daughter of the Béranger-Sasseange married and forgot--in fact she married three times before she eradicated the complete memory of the affair. To-day the walls of Rochechinard are half buried in an undergrowth of vine and shrubs and are nothing more than a sad reminder of the history which has gone before. Three leagues from Saint Marcellin and Beauvoir is Saint Antoine, a sixteenth century townlet of fifteen hundred souls which has endured much, as it has always existed unto this day. It possesses one of the most remarkable and astonishing flamboyant-Gothic churches in all Christendom. During the middle ages Saint Antoine was a place of pilgrimage for Popes and princes, and the Dauphins, by reason of their intimate associations with the distinguished visitors to their country, gained both riches and power from the circumstance. When Dauphiny came to be united to the Crown of France the tradition of Saint Antoine and its life-giving wine continued, and neither François Premier nor Louis XI neglected to make the journey thither. In the case of François Premier there may have been another good, or at least sufficient, reason, for Saint Vallier and Diane de Poitiers were but a few hours away. But that's another point of view, a by-path which need not be followed here, since it would lead us too far astray. Following still the valley of the Isère, one comes to the Chateau de la Sone, at one time one of the strongest fortifications of the lower valley. It was the key to the Royonnais, and a subterranean passage led from its platform underneath the bed of the Isère itself to a chateau of the Dauphins on the opposite bank. With the establishment of a silk-mill here in the chateau in 1771 all romance fled, and there being no more need for a subterranean exit, the passage-way was allowed to fill up. To-day one takes the assertion on faith; there is nothing to prove it one way or another. It was here within these walls that Vaucanson (1709-1782), the "_sorcier-mécanicien_," invented the chain without end, which revolutionized the silk-spinning industry.
