length, breadth, height, and light; the pictures and marble tables that stand in the midst of it, as for its quantity of choice and rare books, if we may believe the monks; they are certainly very well bound and guilded, and if I mistake not, but seldom read. In the vestry, they show priests' copes, where embroidery and pearl with emulation contend whether art or matter renders them more rich and sumptuous; they showed us a cross of very fair pearl, diamonds, and emeralds; it is a very pretty knack, and would not become less such if it changed countreys, I would willingly have undertaken for it if they would have suffered it to pass the Pyreneans, had it been only to show my friends a hundred thousand crowns in a nut-shell. The library I have spoken of, the high altar and monument of their kings, which they call Pantheon (though I know not why, unless because a single round arch like the Pantheon at Rome), are certainly the best pieces of this magnificent fabrick. The high altar is approached by steps of red marble, and invironed by sixteen pillars of jasper, which reach the top of the quire, and cost only a matter of fifty or sixty thousand crowns cutting, between these are niches with statues of guilded brass, and so there are on the side of the tables and praying places. The Pantheon is under the altar, and descended by stairs, though narrow, very light; at the entrance of this rich chappel, a marble shines, whose lustre is heightened by reflexion of the gold, with which all the iron-work and part of that fair stone are overlaid. In the middle of it, and right against the altar, is a fair candlestick of brass, gilded, and in six several niches, twenty-four sepulchres of black marble to receive as many bodies; above the gate are two more. This stately monument is small, but sumptuous, it was finished by the present King, who, about six months since placed there the bodies of Charles the Fifth, Philip the Second, and Philip the Third. The first was most intire; in the niches, on the left, lie the Queens, and the last of them Queen Elizabeth of Burbon. He that preached the day that these seven tombs or sepulchres had bodies laid in them, began by his apprehension to speak in presence of so many kings who had conquered the world, and expressed himself so well, and so highly pleased the King that he got a yearly pension of a thousand crowns. Nothing attaining such perfection as to secure it from the teeth of criticks, the three pieces I have now mentioned, have been attacqued by them. It is objected against the Library, that its entrance suits not with its magnificence and grandeur, and that it stands as if stoln in, and not of the same piece with the rest.
