Leuven 1543–1552 Mercator never committed any of his prison experiences to paper; all he would say p15. Letter to Antoine Perrenot was that he had suffered an "unjust persecution". For the rest of his time in Leuven his religious thoughts were kept to himself and he turned back to his work. His brush with the Inquisition did not affect his relationship with the court and Nicholas Perrenot recommended him to the emperor as a maker of superb instruments. The outcome was an Imperial order for globes, compasses, astrolabe and astronomical rings. They were ready in 1545 and the emperor granted the royal seal of approval to his workshop. They were soon destroyed in the course of the emperor's military ventures and Mercator had to construct a second set, now lost. He also returned to his work on a large up-to-date and highly detailed wall map of Europe which was, he had already claimed on his 1538 world map, very well advanced. It proved to be a vast task and he, perfectionist that he was, seemed unable to cut short his ever-expanding researches and publish: as a result it was to be another ten years before the map appeared.
