The original was organized in synoptic tables: a way to present data in a simple and condensed manner, previously used for astrological tables. Ibn Butlan used them to present not just ways to treat illness and to maintain health, but also ways to prepare food and how and what to grow for health. Later manuscripts were lavishly illustrated, especially after the 14th century. (The illustration is of a facsimile edition made in 1986.)
Ibn Butlan set out the essential elements of health and well-being:
- sufficient food and drink in moderation
- fresh air
- alternations of activity and rest
- alternations of sleep and wakefulness
- secretions and excretions of humors
- the effects of states of mind
If one is not paying attention to these elements, illness occurs.
The Tacuinum includes lists of many vegetables, fruits, nuts, and herbs that are good for treating certain conditions. It also includes the dangers of excess consumption. As the manuscript was copied and distributed, changes were made, and not every copy includes every list. Some added remedies that were not in the original.
The word "humors" was italicized in Ibn Butlan's list because I wanted to draw attention to it. I've ignored discussing the medieval idea of humors for over a decade because I assumed people have already heard of them and I want this blog to focus on all the things that are not generally known. Of course, the details of humors are probably worth talking about. See you tomorrow.
