One of Three Maps Printed by Breitkopf Using Movable Type
Fantastic and uncommon map of the "Source of Wishes," a watershed map showing how fantastical streams from the same source flow to a "quiet, happy country" and through the "land of avarice." This map was printed as part of a project undertaken by Johann Breitkopf between 1777 and 1779 that produced maps using a type-set rather than a copperplate engraving.
The map is a rare example of the short-lived phenomenon of "typometry," a map-printing technique that meshes movable type with movable linework and map symbols. While some typography had been used since the 16th-century to print small letters on otherwise copperplate-engraved maps, the idea of making a map exclusively using this technique had not developed until the late 18th century. Two separate inventors had come up with the concept at nearly the same time. While Breitkopf, a music publisher, had invented the methodology first, he held off printing his maps until 1777 and was beaten by William Haas, a Basle type-founder who published his typeset maps in 1776. This printing method proved more time-consuming than copperplate engraving, and died out quickly, remaining a curiosity into the 19th century.
The map itself is mainly a proof-of-concept work and shows various tools that can be used in mapmaking. It shows a mystical land of mountains, rivers, and cities, all of which relate to the fulfillment of wishes and desires in life.
