British & Exotic Mineralogy
A really lovely unmonetisable enthusiasm:
All 2,242 illustrations from James Sowerby’s compendium of knowledge about mineralogy in Great Britain and beyond, drawn 1802–1817 and arranged by color.
You can dive in and explore or read more about the project and how it was made.
It reminds me of Paul’s project, Bradshaw’s Guide: the both take a beloved artifact of the past and bring it online with care, love, and respect.
