>The Merian plan of Paris was created in 1615 and presents a perspective view looking to the east with a scale of about 1 to 7,000. It originally consisted of two engraved plates 50 x 37 cm each comprising the left and right halves of the map and was printed with 2 columns of portraits (each 50 x 13 cm) on the left and right sides of the respective map halves. The entire assembly was 50 x 101.5 cm. The Merian map was frequently used as the basis of subsequent maps, including those of Visscher (1618), Melchior Tavernier (ca. 1625-1635), Jacob van der Heyden (1630), Christophe Tassin (1634), Dubarle (ca. 1641), Giacomo Lauro (ca. 1642), and Martin Zeiler (1655). In turn, the map of Tassin served as the source of numerous later maps.
