Rumold Mercator

He completed some at the time unfinished projects left after his father's death and added new materials of his own research.

[2] He rose to fame in his father's wake when, in 1587, he published a copy of his father's Ptolemaic map of the world from 1569, revised in its overall graphic design.

[3][4] In 1595, a year after his father's death, Rumold Mercator published a supplement of 34 maps to his father's Tabulae Geographicae map book.

[4] It contains 29 maps, engraved by Gerardus Mercator, of the missing parts of Europe (Iceland, the British Isles and the Northern and Eastern European countries).

In fact, this edition is no more than a single-bound reissue of the four series Tabulae Geographicae with the new addition.
