Perhaps you knew this and know of other instances, but I wanted to share in case it is new to you. My son is currently part of a project digitizing an early French manuscript of "recipes" from the 1500's. Today, he is in a lab at college making one of these recipes with his boss and team on the project. They have obtained a bag full of cochineal insects and are making a red pigment using the original recipe from the manuscript. Not only do I find this wonderfully, nerdy, and cool, I learned something new and I hope you do too.
Here is the iNat taxon page for cochineal scale insects and it describes the uses of this bug in making pigment: https://www.inaturalist.org/taxa/202091-Dactylopius

As of this moment, I cannot remember the details of the French manuscript, but will add that once I hear back. Enjoy!
Edit: manuscript dates from 1500's (corrected above), and it is "Making and Knowing", for more details check out: edition640.makingandknowing.org
