At first the book was intended to be an elaboration of the explanations he had made of the map. But it kept getting bigger. In 1541 Olaus and his brother moved to Rome; Johannes died there in 1544. Following the death of Johannes, Olaus became the Archbishop of Uppsala, the last one–and a hollow appointment since he could not go there. In 1550 Olaus moved to the St. Birgitta Convent in Rome. In 1555 the Latin edition of the Historia was published in Rome. It was a large, folio edition containing a much-reduced version of the Carta Marina.
