1623-335 editions published by Henricus alone. 1633-41 5 editions in conjunction with Jan Jansson. A surviving contract dated March 2, 1630 reveals that Henricus Hondius and his partner Joannes Janssonius hired engravers to produce a number of new map plates copying the work of Jodocus – now in the hands of the Blaeu firm.
