Matthias Quad (1557-1613) engraver and cartographer from Cologne.

Matthias Quad was born and learnt engraving in the Netherlands. An engraver in wood and stone, Quad collaborated with the Cologine publisher Johann Bussemacher to publish a quarto atlas of Europe in 1592. This was expanded into a Geographisches Handtbuch (1599), with more text than maps, and then into a proper atlas, Fasciculus Geographicus (1608).
