Johannes van Loon's very rare sea chart of the northeast passage, from the North Cape to Nova Zemla.
All charts by Joannes van Loon's Sea Atlas are of exceptional rarity.
"Joannes van Loon was an accomplished mathematician and astronomer. His first cartographic involvements were with Theunis Jacobsz during the 1640s. From 1650 he worked with Joannes Janssonius, engraving amongst other worksthe plates for his Celestial Atlas by Cellarius, 1660.
In 1661 he published his first work with his brother, Gillis; the 'Zee Atlas' contained thirty-five maps. In 1666 the plates were Jan Jansson van Waesberge, with whom he then co-published the atlas. This edition was expanded to forty-seven maps, and by 1676 there were fifty."
