In the early 20th century, the Leipzig historian of medicine, Karl Sudhoff, had a stream of medical students edit (or re-edit) different texts from the Codex Salernitanus. In 1921, Conrad Hiersemann chose to re-edit the sections of the De egritudinum curatione ascribed to "Trot'". Hiersemann assumed that the name was masculine, and so expanded it to "Trottus". This erasure of the female author Trota was not questioned until 1985, when John F. Benton, a historian at the California Institute of Technology, discovered the Practica secundum Trotam, the text in the manuscript in Madrid. Benton realized that the Practica had multiple overlaps with therapies ascribed to "Trot'" in the De egritudinum curatione. He was thus able to retrieve the historic woman Trota from the oblivion into which she had fallen for 800 years. However, Benton persisted in his belief that the Trotula texts—which he had proven were originally the work of three separate 12th-century writers—were all male-authored and had nothing to do with the real Trota. What Benton did not realize was that the Practica secundum Trotam also had multiple overlaps with the second of the three Trotula texts, the De curis mulierum (On Treatments for Women). That discovery was made by Monica H. Green, a historian of medieval women's medicine. In 2007, Green established the overlaps and parallels between all four texts witnessing any part of Trota's work: the Salernitan De egritudinum curatione; Practica secundum Trotam; De curis mulierum; and certain cosmetic practices attributed to "Dame Trote" in the Anglo-Norman cosmetic text. Together, these works suggest that Trota's skill extended to most areas of medical practice, save general surgery. Green was not optimistic, however, about what this collected evidence for Trota has to say about the status of women in medicine in 12th-century Salerno. She sees Trota as being on the very edge of literate traditions in medicine: Trota cites no authoritative sources (like Hippocrates or Galen), and there is little by way of physiological theory or explanation of the causes of disease. Green concludes: "Trota did succeed in establishing her stature 'in the forum' as an empiricist. But as a theorist who could impart doctrinae [formal teachings] to students, she had no impact at all." Indeed, Green sees the story of Trota as emblematic of the marginal status of women in the changing spheres of intellectual life in Europe in the 12th century, when universities were first taking hold.
