"So it appears. See to it that the front-door remains open." Gabriel turned about and went away with the plate. The scholar was again alone. The golden light of the lamp fell on his countenance and on the books which lay around him; the white pages rustled under his hand; and his features worked with strong excitement. There was a knock at the door; the expected visitor entered. "Good evening, Fritz," said the Professor to his visitor; "sit in my chair, and look here." The guest, a man of slender form, with delicate features, and wearing spectacles, seated himself at the bidding of his friend, and seized a little book which lay in the middle of a number of open volumes of every age and size. With the eye of a connoisseur he examined the first cover--discolored parchment, upon which were written old church hymns with the accompanying music. He cast a searching glance on the inside of the binding, and inspected the strips of parchment by which the poorly-preserved back of the book was joined to the cover. He then examined the first page of the contents, on which, in faded characters, was written, "The Life of the Holy Hildegard." "The handwriting is that of a writer of the fifteenth century," he exclaimed, and looked inquiringly at his friend. "It is not on that account that I show you the old book. Look further. The Life is followed by prayers, a number of recipes and household regulations, written in various hands, even before the time of Luther. I had bought this manuscript for you, thinking you might perhaps find material for your legends and popular superstitions. But on looking through it, I met with the following passage on one of the last pages, and I cannot yet part with the volume. It seems that the book has been used in a monastery by many generations of monks to note down memoranda, for on this page there is a catalogue of all the church treasures of the Monastery of Rossau. It was a poverty-stricken cloister; the inventory is either small or incomplete. It was made by an ignorant monk, and, as the writing testifies, about the year 1500. See, here are entered church-utensils and a few ecclesiastical vestments; and further on some theological manuscripts of the monastery, of no importance to us, but amongst them the following title: '_Das alt ungehuer puoch von ussfahrt des swigers._'" The Doctor examined the words with curiosity. "That sounds like the title of a tale of chivalry. And what do the words themselves mean! 'The old, immense book of the exit or departure of the _swiger_.' Does _swiger_ here mean son-in-law or a tacit man?" "Let us try to solve the riddle," continued the Professor, with sparkling eyes, pointing with his finger to the same page. "A later hand has added in Latin, 'This book is Latin, almost illegible; it begins with the words _lacrimas et signa_, and ends with the words--here concludes the history--_actorum_--thirtieth book.' Now guess."
