De conservada bona valetudine, scholae Salernitanae opusculum.
Franc.: Apud Chr. Egenolphum 
"The Salerno school produced the most popular health and cure book of the Middle Ages. Entitled Regimen sanitatis, this book was a collection of dietary and pharmaceutical rules written in verse. The original version contained 364 lines. It was annotated and edited by Arnold of Villanova, a leading physician with strong chemical interests, and the book attained a tremendous popularity. After the invention of the printing press, it was published in all major European languages, and it ran through more than 300 editions" (Encyclopedia of Medical History).
"According to ancient tradition, the poem [Regimen sanitatis] was written for the benefit of Robert, Duke of Normandy, son of William the Conqueror. Robert is supposed to have visited Salerno on his way to the First Crusade and again in 1099 on his return after the capture of Jerusalem, where he was treated for a wound in the arm. Robert remained in Salerno for a year enjoying himself at the court of Duke Ruggiero while at home his brother Henry succeeded to the throne of England. Later, Robert tried to remove his brother from the throne but, in 1106, was captured and passed the last 28 years of his life in prison. Most versions of this poem begin with the dedication, "Anglorum Regi," to the King of England, by which title Robert was known since he was at one time the lawful King of England. Some versions, however, are dedicated to the King of France, "Francorum Regi." As time passes and the studies on the origins of the poem multiply, it seems extremely probable that neither the King of England nor the King of France were the personages for whom this rhymed medical advice was composed, but that these collections of verses on health had been current for years in many parts of Italy and Southern France. The present version is s a collection presumably assembled by Arnald of Villanova" (A History of Medicine, Ralph H. Major).
