The Archbishop of Seville, Arias, who was of the same politics, was shortly afterwards sent back to his diocese. The Duke de Montellano replaced him in the presidency of Castile, and a Papal brief, obtained some months after his disgrace, enjoined him not to quit Seville again. There remained Porto-Carrero and the Cardinal d'Estrees, recently nominated ambassador of France. They were the firmest supporters of their cause and the most formidable adversaries of the Princess: Porto-Carrero, by his high position, by the recollection of services rendered at the period of the will; Cardinal d'Estrees, by his influence at the Court of Versailles, by the protection of Noailles, by the energetic support of the entire French party. The strife was fierce; but the resources of Madame des Ursins were equal to the emergency. The Duke de Montellano, president of the Council of Castille, counterbalanced the authority, until then unlimited, of Porto-Carrero; the auditorship of finance, which had always appertained to the prime minister, being taken from him. Weakened by this check and rivalry, the Cardinal abruptly changed his policy and placed himself at the head of the anti-French party; he refused to act with Cardinal d'Estrees, and tendered his resignation. Had he remained firm in that course, probably he might have re-enacted his political part in the ranks of his new friends, and have caused the government great embarrassment. On receiving a letter from Louis XIV., he had the weakness to give way, withdrew his resignation, and resumed his seat at the council board. But factions hate and despise more intensely those who abandon their ranks than those who fight against them: that manoeuvre irritated alike the French and the Spaniards; both, in their turn, abjured. Porto-Carrero was the turn-coat from every cause: as a politician he was annihilated.
