The printer of "Noli Me Tangere" lived in a neighboring street, and, like most printers in Germany, worked for a very moderate compensation, so that the volume of over four hundred pages cost less than a fourth of what it would have done in England, or one half of what it would cost in economical Spain. Yet even at so modest a price, Rizal was delayed in the publication until one fortunate morning he received a visit from a countryman, Doctor Maximo Viola, who invited him to take a pedestrian trip. Rizal responded that his interests kept him in Berlin at that time as he was awaiting funds from home with which to publish a book he had just completed, and showed him the manuscript. Doctor Viola was much interested and offered to use the money he had put aside for the trip to help pay the publisher. So the work went ahead, and when the delayed remittance from his family arrived, Rizal repaid the obligation. Then the two sallied forth on their trip. After a considerable tour of the historic spots and scenic places in Germany, they arrived at Dresden, where Doctor Rizal was warmly greeted by Doctor A. B. Meyer, the Director of the Royal Saxony Ethnographical Institute. He was an authority upon Philippine matters, for some years before he had visited the Islands to make a study of the people. With a countryman resident in the Philippines, Doctor Meyer made careful and thorough scientific investigations, and his conclusions were more favorable to the Filipinos than the published views of many of the unscientific Spanish observers. In the Museum of Art at Dresden, Rizal saw a painting of "Prometheus Bound," which recalled to him a representation of the same idea in a French gallery, and from memory he modeled this figure, which especially appealed to him as being typical of his country. In Austrian territory he first visited Doctor Ferdinand Blumentritt, whom Rizal had known by reputation for many years and with whom he had long corresponded. The two friends stayed at the Hotel Roderkrebs, but were guests at the table of the Austrian professor, whose wife gave them appetizing demonstrations of the characteristic cookery of Hungary. During Rizal's stay he was very much interested in a gathering of tourists, arranged to make known the beauties of that picturesque region, sometimes called the Austrian Switzerland, and he delivered an address upon this occasion. It is noteworthy that the present interest in attracting tourists to the Philippines, as an economic benefit to the country, was anticipated by Doctor Rizal and that he was always looking up methods used in foreign countries for building up tourists' travel.
