Gerard Mercator the Supreme Cartographer

Mercator was born in Rupelmonde in Flanders and studied in Louvain under Gemma Frisius, Dutch writer, astronomer and mathematician. He established himself there as a cartographer and instrument and globe maker, and when he was twenty-five drew and engraved his first map (of Palestine) and went on to produce a map of Flanders (1540) supervising the surveying and completing the drafting and engraving himself. The excellence of his work brought him the patronage of Charles V for whom he constructed a globe, but in spite of his favor with the Emperor he was caught up in the persecution of Lutheran Protestants and charged with heresy, fortunately without serious consequences. No doubt the fear of further persecution influenced his move in 1552 to Duisburg, where he continued the production of maps, globes and instruments culminating in large-scale maps of Europe (1554), the British Isles (1564) and the famous World Map on 18 sheets drawn to his new projection (1569). All these early maps are exceedingly rare, some being known by only one copy. In later life he devoted himself to his edition of the maps in Ptolemy's Geographia, reproduced in his own engraving as nearly as possible in their original form, and to the preparation of his 3-volume collection of maps to which, for the first time, the word 'Atlas' was applied. The word was chosen, he wrote, 'to honor the Titan, Atlas, King of Mauritania, a learned philosopher, mathematician, and astronomer' . The first two parts of the Atlas were published in 1585 and 1589 and the third, with the first two making a complete edition, in 1595 the year after Mercator's death.
