Writings on medicine produced during the time period of the Roman Empire (ca. 27 BCE - 476 CE). These sources display the unmistakable influence of Greek medical literature and practice, as well as some uniquely Roman contributions to the history of medicine. This time period was characterized by growing access to medical knowledge and increasingly advanced surgical practices, while traditional remedies and 'superstitions' such as those described by Pliny the Elder also remained in practice. One can also find in Roman authors such as Celsus invaluable details about medical practices and sects that existed during earlier antique time periods (e.g. the Hellenistic era).
