He started back, and recognised his friend, the testy old Albert, who lived apart from men, and whose solitary house was open to Ferdinand alone: "Do you remember our engagement?" said the hoarse husky voice. "O yes," said Ferdinand: "and will you perform your promise today?" "This very hour," replied the other, "if you like to follow me." They walked through the city to a remote street, and there entered a large edifice. "Today," said the old man, "you must push through with me into my most solitary chamber, that we may not be disturbed." They passed through many rooms, then along some stairs; they wound their way through passages: and Ferdinand, who had thought himself familiar with the house, was now astonished at the multitude of apartments, and the singular arrangement of the spacious building; but still more that the old man, a bachelor, and without family, should inhabit it by himself, with a few servants, and never let out any part of the superfluous room to strangers. Albert at length unbolted the door, and said: "Now, here is the place." They entered a large high chamber, hung round with red damask, which was trimmed with golden listings; the chairs were of the same stuff; and, through heavy red silk curtains covering the windows, came a purple light. "Wait a little," said the old man, and went into another room. Ferdinand took up some books: he found them to contain strange unintelligible characters, circles and lines, with many curious plates; and from the little he could read, they seemed to be works on alchemy; he was aware already that the old man had the reputation of a gold-maker. A lute was lying on the table, singularly overlaid with mother-of-pearl, and coloured wood; and representing birds and flowers in very splendid forms. The star in the middle was a large piece of mother-of-pearl, worked in the most skilful manner into many intersecting circular figures, almost like the centre of a window in a Gothic church. "You are looking at my instrument," said Albert, coming back; "it is two hundred years old: I brought it with me as a memorial of my journey into Spain. But let us leave all that, and do you take a seat."
