The map is notable for its straightforwardness – that is, it does not present any ethnographic vignettes of the era. The Philippines were at that time a vital part of the Spanish Empire, and it made its cartographic debut in Petrus Kaerius’ 1598 map.
A much enlarged Calamianes is partially depicted in the map. The map shows the archipelago “lying on its side”. It takes a while to shake off preconceived constructions and identify our different islands; indeed, those familiar with Old Dutch (Petrus Kaerius is from Amsterdam) would be hard-pressed to recognize the Filipinos described in an accompanying text of Kaerius’ first maps: “inhabitants without laws (inwoenderen zonder Wetten) who are cannibals (Menscheneeters)”. Among the other artists associated with the maps of Petrus Kaerius is Jodocus Hondius.
