1646 Leinster, Ireland

LEINSTER, Johannes Jassonius (1646)In 1645, Joan Blaeu (1598-1673) successfully published an atlas of Great Britain. Blaeu based this atlas on the `Theatre of the Empire of Great Britaine' published by his English colleague John Speed (1552-1629) in 1611. Infected by this success, Blaeu's neighbour, Johannes Janssonius (1588-1664), copied the complete atlas. Janssonius published this pirate issue in 1646. This map of Leinster has been taken from Janssonius' atlas.
