Being at Frankfort on the Main in 1706, I called one day in company with a Jew, and a friend named Frecht, at that time a student in Theology, on an eminent bookseller in whose establishment almost every work was to be met with. We were examining his catalogue when there entered a German officer, who addressed himself to the proprietor in German, and asked him if he was ready to agree to his proposals, or if another merchant should be sought after. Frecht, who formerly was acquainted with the officer, saluted him and was recognised. This gave an opportunity to my friend of asking the officer, whose name was Trawsendorff, what transaction he had with the bookseller. Trawsendorff told him that he had two manuscripts and a very old book in his possession, by the sale of which he expected to raise a sum of money against the approaching campaign, and that the bookseller higgled on 50 Rix-dollars, being unwilling to advance more than 450 for the three works, which he, (the officer), valued at 500. This great sum of money demanded for two manuscripts and a little book excited the curiosity of Frecht, who asked of his friend if he might see the productions which he wished to sell at so dear a rate. Trawsendorff immediately drew from his pocket a parchment envelope, tied with a silk thread, which he opened, and from which he took the three books. We went into the parlour of the bookseller to examine them at our leisure, and the first which Frecht looked at had been printed, but had a title written in Italian instead of its real title, which had been defaced. It ran thus; "Spaccio della Bestia triumphante," and did not appear to be of an ancient date. It struck me as being the same work which Toland translated into English, and printed some years ago, and the copies of which sell very high. The second we looked at was an old Latin manuscript written in a character very difficult to decypher, without any title; but at the top of the first page there were written these words, "Fredric the Emperor wishes health to Otho, his most illustrious and dearest friend. [18]" The work opens with a letter, the first lines of which are as follows; "I will send you as soon as possible a copy of the work on the three most celebrated deceivers of mankind, a work written at my request by a very learned man, and transcribed by my order for my library; and along with it another work written in the same pure and polished style, for, &c." [19] The third was also a Latin manuscript without a title, commencing with a quotation from Cicero.
