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.

Oribasius was a compiler of existing knowledge rather than an original writer. His output was immense; he compiled the Synagoge, an encyclopedic digest of medicine, hygiene, therapeutics, and surgery from Hippocrates to his own times, in 70 volumes. The unwieldiness of the work was probably the reason why he also wrote a synopsis of it. Only 17 volumes survived. Vols. 5 & 6 were completed and issued by Auguste Molinier after the death of Bussemaker and Daremberg. Digital facsimiles of the set from Google Books at this link.

"Born in Pergamum, he [Oribasius] studied medicine at Alexandria under Zeno of Cyprus, and practised in Asia Minor. He became the personal physician of Julian, who took him to Gaul (355). Closely involved in the proclamation of Julian as emperor (361), Oribasius accompanied him until his death in Mesopotamia (363). Banished for a time to foreign courts, Oribasius was soon recalled by the emperor Valens and continued to practise his profession until an advanced age. His principal works are a collection of excerpts from Galen—now lost—and the Collectiones medicae, a vast compilation of excerpts from earlier medical writers, from Alcmaeon of Croton (c.500 bc) to Oribasius' contemporaries Philagrius and Adamantius. Both of these works were written at the behest of Julian. Of the 70 (or 72) books of the Collectiones only 25 survive entire; but the rest can be in part reconstructed from the Synopsis ad Eustathium, and the treatise Ad Eunapium, epitomes of the Collectiones in 9 books and 4 books respectively made by Oribasius himself, and from various excerpts and summaries, some of which are still unpublished. Oribasius was a convinced pagan, and his medical encyclopedia is a product of the vain effort of Julian and his circle to recall the classical past. For the medical historian its importance lies in the large number of excerpts from lost writers—particularly those of the Roman period—which it preserves, usually with a precise reference to the source; Oribasius adds nothing of his own. His work was constantly quoted and excerpted by early Byzantine medical writers, the Synopsis and the Ad Eunapium were twice translated into Latin in Ostrogothic Italy, and Syriac and Arabic translations of portions of Oribasius' work form one of the principal channels by which knowledge of Greek medicine reached the Islamic world" (Robert Browning & Vivian Nutton, Oxford Reference; http://www.oxfordreference.com/view/10.1093/oi/authority.20110803100254300)
