The familiar formula--"must have been"--is out of place here. The necessity does not exist. It seems unlikely that Márquez Torres can have met the members of Mayenne's suite on February 25, 1615; for Mayenne's mission ended two and a half years previously. Mayenne and his attachés left Madrid on August 31, 1612: see Luis Cabrera de Córdoba, _Relaciones de las cosas sucedidas en la Córte de España, desde 1599 hasta 1614_ (Madrid, 1857), p. 493, and François-Tommy Perrens, _Les Mariages espagnols sous le règne de Henri IV. et la régence de Marie de Médicis, 1602-1615_ (Paris, 1869), pp. 403 and 416-417. "Umena" is, as everybody knows, the old Spanish form of Mayenne's title; but no Spaniard ever dreamed of applying this title to the ambassador of whom Márquez Torres speaks. As appears from a letter (dated February 18, 1615) to "old Æsop Gondomar," the special envoy to whom Márquez Torres refers was known as "Mr. de Silier": see Navarrete, _op. cit._, pp. 493-494. Mr. de Silier was the brother of Nicolas Brûlart, Marquis de Sillery, Grand Chancellor of France from September, 1607, to May, 1616. The special envoy figures in French history as the Commandeur Noel Brûlart de Sillery: he and his suite reached Madrid on February 15, 1615 (Navarrete, _op. cit._, p. 493), and they left that city on March 19, 1615 (Perrens, _op. cit._, p. 519). One might have hoped that, as M. de Sillery founded the mission of Sillery near Quebec, his name would be known to all educated Englishmen. His death on September 26, 1640, is mentioned by his confessor, St. Vincent de Paul, in a letter to M. Codoing, dated November 15, 1640. See _Lettres de S. Vincent de Paul_ (Paris, 1882), vol. i., p. 100. I do not know who the above-mentioned "Regent Anne of Austria" is supposed to be. The French Regent who sent Mayenne and Sillery to Spain was Marie de Médicis, mother of Louis XIII. Her regency ended in 1615. In 1615 Anne of Austria, sister of Philip IV., became the wife of Louis XIII. Her regency began in 1643. It would almost seem as though the earlier French Queen-Regent had been mistaken for her future Spanish daughter-in-law, or, as though the writer were unaware of the fact that the "Regent Anne of Austria" and the "Infanta Ana" were really one and the same person. But the whole passage indicates great confusion of thought, as well as strange misunderstanding of Navarrete's words and of the document printed by him.
