Hippocrates’ life is traditionally dated to the mid-5th century BCE; later ancient and modern accounts place his birth on the island of Kos, which became closely associated with Coan medical teaching.
By the mid-5th century BCE, Greek medical writing associated with multiple centers (including Kos and Cnidus) began to circulate in Ionic Greek, laying foundations for what later became known as the Hippocratic Corpus.
The treatise Airs, Waters, Places is generally dated to the 5th–4th century BCE and is notable for arguing that environment and local conditions shape patterns of disease—an early, systematic ecological approach to health.
On Ancient Medicine (commonly dated to the late 5th century BCE) defends medicine as a practical craft grounded in observation and experience, criticizing speculative theorizing disconnected from clinical work.
Several books of Epidemics (notably I and III) are dated to the late 5th century BCE and exemplify a Hippocratic hallmark: careful bedside observation, day-by-day case notes, and prognosis based on patterns in symptoms.
Often dated to around 400 BCE, On the Sacred Disease argues that epilepsy is not divine punishment but a bodily disorder with natural causes—an influential statement of anti-supernatural, rational explanation in Greek medicine.
Composed around 400 BCE and traditionally associated with Polybus (Hippocrates’ circle), On the Nature of Man presents the four-humor framework and treats disease as imbalance—an idea that became central to later Greek and Roman medical theory.
The Hippocratic Oath, part of the broader Hippocratic tradition though not securely attributable to Hippocrates himself, is commonly dated to the 5th–4th century BCE. It became a durable reference point for medical ethics and professional conduct.
Hippocrates is traditionally said to have died in Thessaly (often specified as Larissa) in the later 4th century BCE; exact details remain uncertain, but the approximate dating is widely repeated in reference works.
Archaeological and historical discussions place an early monumental phase of the Asklepieion on Kos in the Classical period (with later Hellenistic rebuilding). The sanctuary connected cult practice with healing, and Kos became a prominent center for medical teaching.
In the Hellenistic period, scholarship and library-building at Alexandria encouraged collecting and organizing earlier Greek texts. Medical treatises later grouped as the Hippocratic Corpus were likely consolidated in this broader Alexandrian bibliographic environment.
By the end of the Classical-to-early Hellenistic transition, Hippocrates’ reputation and the texts associated with his name had become an enduring point of reference for later medical authors—helping define medicine as a teachable craft emphasizing observation, regimen, and prognosis.
