4.20 TS – Greek Medicine from Byzantium Beyond Byzantium. Fortune of a Compilation and a Translation: The Peri diaitēs by Theophanes Chrysobalantes in the Translation by Giorgio Valla

The indirect tradition of ancient medical knowledge has also been entrusted to a precious and neglected vehicle of transmission, namely the sylloge of the Late Antiquity and Byzantine period. A significant example, in this sense, is provided by the compilation activity of a physician of the court of Constantine VII Porphyrogenitus, Theophanes Chrysobalantes. All of his medical handbooks, in a chain of sources yet to be explored, draw on authors already known, partially known or sometimes unknown to the Latin West. Even the Περὶ διαίτης/De alimentis, in its thematic homogeneity, is articulated in a sort of cento plot of which it is almost always possible to recognize the sources. The influence of this ἐγχειρίδιον is amplified through its use in Latin translation by the physician and humanist Giorgio Valla from Piacenza. Mut. gr. 61 is the antigraph on which Valla prepared its first Latin translation, published in Venice by Simone Bevilacqua in 1498, and the text inserted within the De oeconomia section of bk. 42 of his De expetendis et fugiendis rebus opus (Venice, 1501). The spread of both the incunabulum and the “encyclopedia” provides us with the opportunity for a textual journey that due to a need for compilation leads, through an interesting process of linguistic and cultural transcoding, to the construction of the modern medical lexicon for nutraceutics and digestive processes.
