²⁶ This is born out by Roelof van Gelder (note 19 above), who established that binding did not commence until the early 1670s (it was not completed at Van der Hem's death in 1678). Material dated up to 1677 was incorporated in the Atlas: Roelof van Gelder 1992, p.16.

²⁸ Amsterdam became the major mapmaking centre of Europe in the seventeenth century; Jodocus Hondius took over Mercator's Antwerp business and with it his unique plates, and settled in Amsterdam. Hondius was succeeded by his son Henry, and he in turn by Jan Jansson, who married into the Hondius family. In 1671, when Patin was in Amsterdam, Jansson had died, but the business continued to publish some maps. Patin's comment on navigational maps indicates that it was Blaeu's business he saw. Blaeu's printing works were destroyed by fire in 1672. See Tooley, R.V., Maps and Mapmakers, (1978)Google Scholar.

²⁹ In 1847 twenty-eight large drawings, mostly by Schellinks, were removed from their original places and kept in a separate box in the director's room (Ausseren, 37).

³² The auction catalogue (see note 27 above) of Van der Hem's library includes 24 pages ‘illuminatarum’ headed ‘A large quantity of unusual and rare illustrative material, bound books of drawings of the best Italian, French, German, and Dutch artists … collected with great effort and expense … illuminated most beautifully by D.J. van Santen …’ Clearly when Van der Hem died in 1678, there was still a large amount of material similar to that incorporated in the Atlas, which was probably intended for that purpose. We did not find any drawings by Schellinks in this catalogue, which seems to indicate that Van der Hem used all the drawings he bought, in the atlas.
