Two weeks ago we talked about lapis lazuli and its use in blue inks, although it was not used in the coat of arms in 10a 189 (see the post here). This week we’ll be looking at the green ink used in 10a 233 – Galen’s De crisibus libri III, in the translation of Gerard of Cremona.
The Library’s copy of De crisibus was written in first half of the 13th century (1200 – 1250) in France. We will learn more about Galen (129 – circa 200/216) in subsequent posts, but he was a Greek physician, surgeon and philosopher in the Roman Empire.
