These are cookies! Or, as the British artist, Dr Ella Hawkins, calls them: biscuits.
Her caption:
Maria Sibylla Merian (1647-1717) was a naturalist and nature artist. She studied insects, flowers, and animals in various parts of the world, publishing her findings in a series of illustrated volumes.
Here are some of Merian’s celebrated illustrations in biscuit (cookie) form.
The original paintings form part of the Royal Collection, and are watercolour on vellum.

I celebrated Maria Sibylla Merian in an earlier post in 2017.
