Peacay, the guy behind BibliOdyssey, also has a Tumblr blog, where he posts extra content with less in-depth research -because there are more great pictures from literature of the past than there is time to prepare them! Today, he posted some watercolors he's saved for ages from a Marine Atlas dated between 1820 and 1840, by by Mori Jiang Yuan Shou. See more of them at BibliPeacay.
