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.
Adomnán
Adomnán's most important work, and the one for which he is best known, is the "Vita Columbae" (i.e. "Life of Columba"), a hagiography of Iona's founder, Saint Columba, probably written between 697 and 700. The format borrows to some extent from Sulpicius Severus' "Life of Saint Martin of Tours". Adamnan adapted traditional forms of Christian biography to group stories about Columba thematically rather than chronologically, and present Columba as comparable to a hero in Gaelic mythology. Wetherill suggests that one of the motivations for writing the Vita was to offer Columba as a model for the monks, and thereby improve Adomnan's standing as abbot. The biography is by far the most important surviving work written in early medieval Scotland, and is a vital source for our knowledge of the Picts, as well as a great insight into the life of Iona and the early medieval Gaelic monk.
