The house in which the events of this history occurred stands at about the middle of the rue de Paris, and has been known at Douai for more than two centuries as the House of Claes. The Van Claes were formerly one of the great families of craftsmen to whom, in various lines of production, the Netherlands owed a commercial supremacy which it has never lost. For a long period of time the Claes lived at Ghent, and were, from generation to generation, the syndics of the powerful Guild of Weavers. When the great city revolted under Charles V., who tried to suppress its privileges, the head of the Claes family was so deeply compromised in the rebellion that, foreseeing a catastrophe and bound to share the fate of his associates, he secretly sent wife, children, and property to France before the Emperor invested the town. The syndic’s forebodings were justified. Together with other burghers who were excluded from the capitulation, he was hanged as a rebel, though he was, in reality, the defender of the liberties of Ghent. The death of Claes and his associates bore fruit. Their needless execution cost the King of Spain the greater part of his possessions in the Netherlands. Of all the seed sown in the earth, the blood of martyrs gives the quickest harvest. When Philip the Second, who punished revolt through two generations, stretched his iron sceptre over Douai, the Claes preserved their great wealth by allying themselves in marriage with the very noble family of Molina, whose elder branch, then poor, thus became rich enough to buy the county of Nourho which they had long held titularly in the kingdom of Leon. At the beginning of the nineteenth century, after vicissitudes which are of no interest to our present purpose, the family of Claes was represented at Douai in the person of Monsieur Balthazar Claes-Molina, Comte de Nourho, who preferred to be called simply Balthazar Claes. Of the immense fortune amassed by his ancestors, who had kept in motion over a thousand looms, there remained to him some fifteen thousand francs a year from landed property in the arrondissement of Douai, and the house in the rue de Paris, whose furniture in itself was a fortune. As to the family possessions in Leon, they had been in litigation between the Molinas of Douai and the branch of the family which remained in Spain. The Molinas of Leon won the domain and assumed the title of Comtes de Nourho, though the Claes alone had a legal right to it. But the pride of a Belgian burgher was superior to the haughty arrogance of Castile: after the civil rights were instituted, Balthazar Claes cast aside the ragged robes of his Spanish nobility for his more illustrious descent from the Ghent martyr.
