Rosettes and Revelations Pt.1: The Holy City - Koen Gheuens and Cary Rapaport

[ReneZ]

Hear are a few examples of map waves and hashing:

There are 4 examples showing hashing where water meets land. And there are 4 examples showing water represented by blue and wavy lines.

While I always enjoy seeing examples of historical images, many of these are not at all from the early 15th century. Some could be older but some are definitely newer. I only checked the Ferrara map and it is from 1679 (approx).
