Anonymus Londinensis is the name given to an anonymous Ancient Greek author of approximately the 1st century AD whose work On Medicine is partially preserved in a papyrus in the British Library. It ranks as the most important surviving medical papyrus and provides important information about the history of Greek medical thought.
''On Medicine''
While only fragments survive of some portions of the text, the papyrus containing the work of Anonymus Londinensis is exceptionally well preserved, with 3.5 meters of the roll largely intact, containing almost 2,000 lines of text in 39 columns. It seems to be an unfinished draft in the hand of the author, who compiled, digested, and manipulated various sources as he wrote, so that we may even observe the process of his thinking as he writes. The text consists of three parts: a series of definitions related to the affections of the body and soul, a doxographical part, and a physiological part.
''Menoneia''
The doxographical part is a survey of 5th and 4th century writers on the causes of disease, following a source called "Aristotle" but usually ascribed to Aristotle's pupil Meno and identified with the title Menoneia mentioned in Plutarch's Quaestiones convivales , 377c. This work would have been part of the early Peripatetic project to survey all of the most important fields of knowledge. The views of some twenty physicians are reported, with Plato cited more than any other authority, even Hippocrates. The authorities are classified into two groups, one holding that disease is caused by residues of food, the other by disturbances in the balance of the bodily elements. Hermann Diels had suggested that Anonymus Londinensis knew this Peripatetic doxography through the Areskonta of Alexander Philalethes, but there is little plausible justification for this view.
On physiology
The final, incomplete, section of the work discusses physiology in a manner influenced by dialectical argument. Only the views of Aristotle and subsequent authors are considered, including Herophilus, Erasistratus, Asclepiades of Bithynia, and Alexander Philalethes. This interesting section contains ideas about vitality and motion, nutriment, the various emanations from the body, digestion, veins and arteries, and the invisible "pores."
Editions and translations
The papyrus was first described by Frederic G. Kenyon in 1892. Diels produced the first edition of the Greek text, which was published in 1893 by the Prussian Academy of Sciences as volume III, part 1, of Supplementum Aristotelicum. A German translation of Diels' text by Heinrich Beckh and Franz Spät was published in 1896. W.H.S. Jones reprinted Diels' Greek text together with his own English translation and commentary in The Medical Writings of Anonymus Londinensis, Cambridge University Press, 1947. A new Teubner edition of the Greek text by Daniela Manetti was published in 2011, while Antonio Ricciardetto published a critical text in 2013 and reprised it as a Greek-French bilingual text in the Collection Budé series in 2016. An edition by Jackie Pigeaud has also been announced.
