Matthias Quad (1557–1613) was an engraver and cartographer from Cologne.
He was the first European mapmaker to use dotted lines to indicate international borders.
[1] Matthias Quad was born and learnt engraving in the Netherlands.
An engraver in wood and stone,[2] Quad collaborated with the Cologne publisher Johann Bussemacher to publish a quarto atlas of Europe in 1592.
[3] This was expanded into a Geographisches Handtbuch (1599), with more text than maps, and then into a proper atlas, Fasciculus Geographicus (1608).
