Copper engraving, mm 370x500. From “Accurata Orbis antiqui Delineatio”, Janssonius’ historical atlas with text by Hornius, published as volume VI of his Atlas Novus. Johannes Janssonius (1588 - 1664) was born in Arnhem, Holland. He was the son of a printer and bookseller and in 1612 married the daughter of Hondius. In 1616 Jansson produced his first maps influenced by Blaeu. In the mid 1630s Jansson partnered with his brother-in-law, Henricus Hondius, to produce his important work, the eleven volume Atlas Major. About this time, Jansson's name also begins to appear on Hondius reissues of notable Mercator/Hondius atlases. Georg Horn (1620 - 1670) german historian and professor, composed a number of historical essays but is best known for composing the text to accompany Johannes Jansson's historical atlas.
