Warned by his father's mistakes, he determined to make the most trifling acts of his old age contribute to the success of the drama which was to take place at his deathbed. Therefore, the greater part of his wealth lay buried in the cellars of his palace at Ferrara, whither he seldom went. The rest of his fortune was invested in a life annuity, so that his wife and children might be interested in keeping him alive. This was a species of cleverness which his father should have practiced; but this Machiavellian scheme was unnecessary in his case. Young Philippe Belvidéro, his son, grew up a Spaniard as conscientiously religious as his father was impious, on the principle of the proverb: "A miserly father, a spendthrift son." The Abbot of San Lucas was selected by Don Juan to direct the consciences of the Duchess of Belvidéro and of Philippe. This ecclesiastic was a holy man, of fine carriage, well proportioned, with beautiful black eyes and a head like Tiberius. He was wearied with fasting, pale and worn, and continually battling with temptation, like all recluses. The old nobleman still hoped perhaps to be able to kill a monk before finishing his first lease of life. But, whether the Abbot was as clever as Don Juan, or whether Doña Elvira had more prudence or virtue than Spain usually accords to women, Don Juan was obliged to pass his last days like a country parson, without scandal. Sometimes he took pleasure in finding his wife and son remiss in their religious duties, and insisted imperiously that they should fulfil all the obligations imposed upon the faithful by the court of Rome. He was never so happy as when listening to the gallant Abbot of San Lucas, Doña Elvira and Philippe engaged in arguing a case of conscience.
