owner once blew so terrible a blast that all the birds dropped dead in the forests of Roncesvalles and it was heard for twenty miles around. The earliest historical knowledge we have of a light-house here is from a charter of the fourteenth century, by which we learn that the Black Prince built a tower on the cliff of Cordouan, with a chapel dedicated to the Blessed Virgin, kept by a hermit. In 1409 the hermit’s name was Geoffroy de Lesparre, who subsisted by levying two _grossos sterlingorum_ on every vessel from Bordeaux laden with wine—a toll that Henry IV. of England authorized him to double. As for the modern tower of Cordouan, Louis de Foix was “Le gentil ingénieur de ce superbe ouvrage.” He was one of the architects employed by Philip II. of Spain in building the Escorial, and the inventor of the mechanism by which the waters of the Tagus were carried to the highest part of the city of Toledo. Some curious things are related of this ingenious architect while in Philip’s service. The ill-conditioned prince, Don Carlos, seems to have placed confidence in him; for he commissioned De Foix to furnish him with a book heavy enough to kill a man with a single blow. The architect made one of twelve tablets of stone, six inches long and four broad, bound in steel covers embossed with gold, which weighed over fourteen pounds, and might have had for its motto the excellent _mot_ of Callimachus on the danger of weighty books. De Thou relates the account of this momentous tome, which is also referred to in the list of Don Carlos’ expenses, and says De Foix told him the idea was by no means an original one of the prince’s, but suggested by a similar volume improvised in his grandfather’s time by Don Antonio de Acuña, Bishop of Zamora, who, confined in the castle of Simancas for taking part in the rebellion of the Comuneros, covered a brick of the size of his breviary with leather, and with this volume of decisive theology killed his keeper and made his escape. Perhaps Don Carlos overlooked the fate of the bishop, who was overtaken by the keeper’s son and hanged on the battlements of the castle of Simancas. All who have visited the Armeria Real at Madrid will remember the armor of this belligerent prelate. De Foix also invented several curious clocks for Don Carlos, who seems to have inherited Charles V.’s taste for chronometrical instruments. Every one knows the anecdote of the servant who, suddenly entering the emperor’s room one day, overthrew the table and broke to pieces the thirty watches on it. The emperor laughed and said: “You are more successful than I, for you have discovered the only means of making them all go alike.” Among these clocks of complicated mechanism made for the prince by De Foix was one in the shape of an antique temple adorned with columns, that indicated the hours, days, months, and other things.
