I have heard of King Arthur. But was not knowing anything in this detail. Thanks for the article.
I have a small concern regarding the license of images used. Maybe you want to check if these have no copyright issues. You should mention the license and attribute it properly according to steemSTEM copyright guidelines for the articles.
I took care of it :D
Yes your images are okay now. But you need to mention the license info and attribution I guess. Like if a license is CC version 4, you should mention those details.
