Editing Theatrum Orbis Terrarum (section)

The moneyed middle class, which had much interest in knowledge and science, turned out to be very much interested in the convenient size and the pooling of knowledge. For buyers who were not strong in Latin, from the end of 1572, in addition to the Latin version, Dutch, German and French editions were published. 
This rapid success prompted the Ortelius Theatrum to constantly expand and improve. In 1573, he released 17 more additional maps under the title ''Additamentum Theatri Orbis Terrarum'', bringing the total at 70 maps. By Ortelius' death in 1598, there were twenty-five editions that had appeared in seven different languages.
