A Syriac palimpsest parchment codex of Galen’s On the Mixtures and Powers of Simple Drugs—or On Simple Drugs—has recently surfaced. Interestingly, it was sold to a private German collector in the 1920s and did not resurface until 2002, when it was purchased by a "wealthy collector of rare scientific material in Baltimore." Missing pages have been identified at the National Library of France, the Vatican, and St. Catherine's monastery. It is now being researched by scholars. Read the full story here.
