 The title is mentioned only in Pliny, and none of the known fragments of Soranus can be attributed to this large-scale work with certainty.Soranus's innovation in providing a table of contents — most likely a list of "capita rerum" ("subject headings") at the beginning — suggests that the "Epoptides" was an encyclopedic or compendious prose work.Alternatively, the "Epoptides" may have been a long didactic poem.
