Matthäus Merian der Ältere (or "Matthew", "the Elder", or "Sr."; 22 September 1593 – 19 June 1650) was a Swiss-born engraver who worked in Frankfurt, Germany for most of his career, where he also ran a publishing house.
In 1620, when Oppenheim was destroyed by fire during the Spanish occupation, they moved back to Basel, but three years later returned to Germany, this time to Frankfurt.
With Martin Zeiler (1589–1661), a German geographer, and later (c. 1640) with his own son, Matthäus Merian (der Jüngere, i.e. "the Younger" or "Jr.") (1621–1687), he produced a series of Topographia.
It includes numerous town plans and views, as well as maps of most countries and a World Map—it was such a popular work that it was re-issued in many editions.
He undertook the engravings for the encyclopaedic work of insect natural history De Serpentibus, compiled by John Jonston.
