One of the most distinctive of the Elzevir undertakings in foreign parts was the branch House established in 1632 in Copenhagen. The Danish community proved to be a good customer as well for the publications from Holland as for the books which the Elzevirs were able to supply to advantage from Germany, Italy, and France. One evidence of the importance attached by the Elzevirs to this branch House in Copenhagen was the printing (in 1642) of a separate catalogue of the books there offered for sale. The first of the Elzevirs to visit Denmark was probably Louis (the second) in 1632. There are references to later visits by him in 1634, and in 1637. On the occasion of his first visit, he had opened a shop and appointed a permanent representative. The record of the town library of Copenhagen contains an entry of the payment to Elzevir, in 1632, of two hundred and sixty-four _rigsdaler_ for books imported, and of a further payment, in 1634, of one hundred and twenty _rigsdaler_.[137] In 1650, it was Daniel who represented the House in the North, sojourning in both Sweden and Denmark, and having for his travelling companion one of his famous authors, Nicholas Heinsius. While Daniel Elzevir was in Sweden, he received a proposition from Queen Christina to establish a printing and publishing concern in Stockholm. Christina of Sweden was a daughter of Gustavus Adolphus. She was at the time but twenty-eight years of age, but she had already given evidence of a strength of character and a brilliancy of intellect that made her personality a very distinctive one. She was a scholar of varied attainments and a great collector of books, and she was ambitious to make her capital city a literary centre for the North of Europe. Mr. Myrop speaks of the proposition made to Elzevir as being a very flattering one, and it is easy to understand that the ambitious Queen could hope to secure in her literary undertakings the kind of service she required from a House like the Elzevirs, who were alike the greatest publishers, the most distinguished printers, and the most extensive booksellers of their time. For some reason, however, the suggestion of a Stockholm branch did not happen to fit in with the policy of the House, and the proposition was declined.[138] A few years later, a printing and publishing concern was established in Stockholm, under the protection of King Charles Gustavus, by Johann Janssons of Amsterdam. The visit to Stockholm of Daniel Elzevir and his negotiations with Christina preceded by but four years the abdication of the brilliant but erratic Queen, which took place in 1654. She became a Catholic (her intention of abandoning Protestantism was one ground for her abdication) and made her home in Rome. She brought with her to Rome no less than 2145 books in manuscript, and after becoming a Roman citizen, she added to the collection several hundred valuable works. With a few exceptions, the entire collection now rests in the Vatican.
