A person in blue hidden in foliage is pulling strings attached to net traps to catch turtle doves on the ground, with birds flying around a nearby leafy tree. Origin: Tacuinum sanitatis in medicina. Cod. Vindob. ser. nov. 2644, folio. 69r. Tacuinum Sanitatis is a medieval handbook based on the Taqwim as-sihhah, an 11th century Arab medical treatise by Ibn Butlan of Baghdad. When translated into Latin in 13th-century, Taqwim (تقيم) was latinised as Tacuinum. The handbook sets forth the six essential elements for well-being: sufficient food and drink in moderation, fresh air, alternations of activity and rest, alternations of sleep and wakefulness, secretions and excretions of humours, and finally the effects of states of mind.
