The Asclepius situated below the Acropolis had an ancient hospital for the mentally ill. Galen the most fanous doctor in the ancient Roman Empire and personal physician to Emperor Marcus Aurelius practised there.
Pergamum's library at the Acropolis was the second best in the ancient Greek civilisation. There were 200,000 volumes in the library. Mark Anthony took the whole collection to Alexandria in Egypt as a wedding gift for Cleopatra. Parchment (pergaminus or pergamena) was invented here when there was a lack of papyrus for writing.
