Gerard and Cornelis de Jode
Most of the maps sold by De Jode have prototypes of Italian or German origin. Apart from his numerous separately published maps, Gerard de Jode is best known for his atlas, Speculum Orbis Terrarum, which was published in 1578. Part of the engraving was done by himself, and part by brothers Jan and Lucas van Doetecum.
Gerard de Jode and Abraham Ortelius, who both worked as map sellers, were competitors and often had strained relations.
After the death of Gerard de Jode in 1591, the business was carried on by his widow, Pascale van Gelder and his son, Cornelis (1568-1600). More a publisher than an engraver, the latter reissued the Speculum in 1593, adding new maps and revising others. Despite all its deficiencies, the Speculum must have had a good reputation.
