Aretaeus of Cappadocia is a Greek ἱατρός of the Roman Imperial centuries; later writers often place him in the 2nd century CE. Dates of his life are uncertain. Later writers group him with those who speak of πνεῦμα, and with readers of the older Hippocratic books.
What this site holds are four books in an Ionic Greek meant to sound like Hippocrates: On the Causes and Signs of Acute Diseases, On the Causes and Signs of Chronic Diseases, Treatment of Acute Diseases, and Treatment of Chronic Diseases.
The books speak of πνεῦμα. They are not Galen’s. They survive through a thin Byzantine manuscript stream and were little read in the Latin West until the 16th century.
