The origin of the Corpus Hippocraticum from ancestors to Codices Antiqi: the Codex Vaticanus Graecus 276.
The Corpus Hippocraticum (C.H.) was originated by the collection of writings of late Greek medicine, mainly of Hippocratic school. The original works have been transmitted through rolls of papyrus or parchments as single treatise or small group of treatises until the IX-X century A.D., when in Byzantium were active scriptoria devoted to collect classical works of both religious and profane argument. Under the auspices of Emperor Constantine Porphyrogenete (tenth century), the tendency to encyclopedism of that period induces large collections of thematic works, i.e. about classical philosophy, astronomy, mathematics or medicine, as may be argued by the content of the Encyclopedia [2 Greek words] (X century). Vetusti codices, such as Vindobonensis med. IV, Parisinus 2253 (A), Laurentianus 74.7 (B), Marcianus Venentus gr. 269 (M) and Vaticanus gr. 276 (V) represent witnessing of the formation of the C.H.: codicological analysis suggests that these manuscripts have been handwritten in scriptoria of Byzantium's area, then carried in Western Europe. Since the first testimony of V is at the Royal Court in Palermo, the Norman Kings played a relevant role in tracing codices from Byzantium to Sicily, as well as Cardinal Bessarion to Rome and Venice.
