Massage
One of the greatest Persian medics was Avicenna, also known as Ibn Sina, who lived from 980AD to 1037AD. His works included a comprehensive collection and systematisation of the fragmentary and unorganised Greco-Roman medical literature that had been translated Arabic by that time, augmented by notes from his own experiences. One of his books, "Al-Qānūn fī aṭ-Ṭibb" (The Canon of Medicine) has been called the most famous single book in the history of medicine in both East and West. Avicenna excelled in the logical assessment of conditions and comparison of symptoms and took special note of analgesics and their proper use as well as other methods of relieving pain, including massage.
History of astrology
For example, Avicenna’s 'Refutation against astrology' "Resāla fī ebṭāl aḥkām al-nojūm", argues against the practice of astrology while supporting the principle of planets acting as the agents of divine causation which express God's absolute power over creation. Avicenna considered that the movement of the planets influenced life on earth in a deterministic way, but argued against the capability of determining the exact influence of the stars. In essence, Avicenna did not refute the essential dogma of astrology, but denied our ability to understand it to the extent that precise and fatalistic predictions could be made from it.
