i found this:

its a seamap from 1537.
its filled with seamonsters and inaccuracies, but its not too far off from reality.
you can identify the major localities pretty decently.
the bible is just like this seamap.
take those giant ship-sinking seamonsters with huge grains of salt, and look for things that seems more plausible. be very critical of everything.
