From a clinical point of view, the two works of Caelius Aurelianus, which were translated into Latin from Greek originals by Soranus of Ephesus that were later lost, represent the high-point of Graeco-Roman medical achievement. Soranus (fl. circa 150 CE), was the chief representative of the methodic school of medicine. Besides his writings on gynecology and obstetrics that survived, Soranus left works on chronic and acute maladies—Tardae or Chronicae passiones, in five books, and Celeres or Acutae passiones in three books, which were preserved through Caelius's translations. The Latin translations show that Soranus possessed considerable practical skill in the diagnosis of both ordinary and exceptional diseases. The translations are also important for their references to the methods of earlier medical authorities.

This is first edition of Caelius's Tardarum passionum (Chronic diseases ), edited by Johannes Sichard. On the verso of the title page the editor provided a list of about 50 ancient Greek physicians referred to in Caelius's text.

Garrison described Caelius / Soranus as a 5th century neurologist who gave one of the best early descriptions of epilepsy, including its convulsive and comatose forms, and the tendency of victims of vertigo to become epileptic. Caelius also distinguished between sensory and motor impairment, and between spastic and flaccid paralysis.

The first edition of Caelius's / Soranus's other work—Acute diseases – Liber celerum vel acutarum passionum, was edited by Johann Guinter von Andernach and published in Paris at the press of Simon de Colines in 1533. Both that and Sicart's edition of 1529 were based on Latin manuscripts that have since disappeared. No other medieval codices of these texts survived.

The four works by Oribasius also edited by Sicard for this 1529 printing represent the first editions in Latin of the texts involved. Like Caelius and Soranus, Oribasius was also a major compiler. Oribasius, a pagan, was physician to the Emperor Julian (the Apostate) in the period of Late Antiquity. Digital facsimile of the 1529 edition from Google Books at this link.
