One of the most influential medical treatises handed down to Muslims was De Materia Medica, by a first-century b.c. Greek physician in Cilicia (southern Anatolia). The left page concerns making medicine from honey and water, prescribed to cure weakness and loss of appetite. A doctor holds a gold cup while stirring the boiling honey and water in a cauldron as he prepares to scoop it up for the seated patient. The architectural setting suggests that the drugs are being produced in a pharmacy like those attached to hospitals in the Seljuq lands. In the illustration on the right, a doctor and his assistant or patient stand on either side of a sieve through which grapes are pressed and then combined with brine and an onion-like herb to produce a medicine to cure digestive disorders.
