In addition to the treatises referred to above,--treatises which are known to have been written by the authors to whom I have credited them,--the _Collectio Salernitana_ contains several of which the authorship is not known. One of these, which bears the title “_De Aegritudinum Curatione_,” is reputed to furnish a better account of the special pathology and therapeutics taught at the Medical School of Salerno during the height of its celebrity than is to be found in any of the other treatises. In one part of the book--that, namely, in which local affections are discussed--the anonymous author gives in succession the opinions held by the seven leading teachers of the school (Platearius II., Cophon II., Petronius, Afflacius, Bartholomaeus, Ferrarius and Trotula) with regard to each one of a certain number of local diseases; thus enabling the reader to obtain a very fair idea of what was the condition of medical science at Salerno during the twelfth century of the present era. The famous didactic poem known as the “School of Salerno” (_Schola Salernitana_) and also as the “Code of Health of the School of Salerno” (_Regimen Sanitatis Salernitanum_), was composed originally about 1100 A. D. It was clearly intended in the first instance for the guidance of laymen in matters relating to diet, the conservation of health and the prevention of disease; but from time to time, as the years rolled on, there were added to it several sections which changed materially the character of the poem. From a mere code of health it became eventually a fairly complete cyclopaedia of medicine in versified form; the number of the verses having increased fully tenfold during this long period. The poem, in its latest state, is arranged in ten principal sections, as follows: Hygiene (8 chapters); materia medica (4 chapters); anatomy (4 chapters); physiology (9 chapters); etiology (3 chapters); significance of different signs (24 chapters); pathology (8 chapters); therapeutics (22 chapters); nosology (20 chapters); and the practice of medicine as actually experienced (5 chapters). The work has been translated into nearly every modern language, and, according to an estimate which was made in 1857, there are in existence no fewer than 240 different editions. The most recent of these is the French translation made by Meaux Saint-Marc and published by him (2d edition) in Paris in 1880. There are two English versions--that by A. Croke (Oxford, 1830), and the more recent one by John Ordronaux (Philadelphia, 1871).
