The Travels of Marco Polo

The earliest western mention of camphor is in the same prescription by the physician Aëtius (circa A.D. 540) that contains one of the earliest mentions of musk. The prescription ends: “and if you have a supply of camphor add two ounces of that.” (Aetii Medici Graeci Tetrabiblos, etc., Froben, 1549, p. 910.)
