Abraham Ortelius was a cartographer and publisher, and the first person to publish an atlas as we now know it. He began his career as a map colourist, enrolling in the Guild of St Luke in Antwerp in 1547, and appearing in the books of the Plantin publishing house in 1558 as a “peintre des cartes”. He lived with his sister Anna, who was also a map colourist; one of his clients specifically requested an atlas coloured by her. He dealt in maps and books to supplement his income, and met Gerard Mercator at the Frankfurt book fair in 1554. He moved into the publishing side of the business in 1561, after he assembled a collection of maps of Europe for his patron Gillis Hooftman, and three years later he produced his own eight sheet world map, Typus orbis terrarum. Only one copy survives. He then began his magnum opus, Theatrum orbis terrarum, the first atlas in the modern sense of the world. Although collections of maps had been bound together in the past, this was made according to principles laid down by its editor rather than a customer. It was also the first to make the maps uniform in style and scale and, unusually, the individual maps were not issued for sale beforehand, as Ortelius thought of them as a coherent whole. It also contained the first accurate European map of Japan.
