In 1535-36 Mercator, together with Van den Heyden and Gemma Frisius constructed a terrestrial globe though on this occasion Mercator's involvement was primarily that of engraver. In fact, this was the first time copper plates had been used to print the paper sections for the globe and consequently it was possible to achieve far greater detail than would have been the case had wood blocks been used.
Mercator produced his first actual map, of Palestine, in 1537.

In 1544 Mercator was arrested and charged with heresy partly because of his protestant beliefs but fortunately was released after seven months imprisonment since nothing could be found to incriminate him.
