Every time I see an article online about an archaeological discovery, I always think, that map reminds me of RPG maps.
One can easily find them by googling the phrase “archaeological field maps.” Some are of buildings, fortifications, tombs, or entire cities. All of them are interesting and seem to give me ideas.
In addition to finding maps when searching that phrase, there are links for courses on how to draw those maps and specific projects and their maps.
The look of these old maps makes me wonder if the originators of D&D were inspired by these maps, or secondarily influenced by them through the use of similar maps in war gaming? I have not yet finished Jon Peterson’s tome to know if he touches on that, but it definitely makes me wonder.
