Hippocrates is known as the "father of medicine" in ancient Greece. Living during the 5th century BCE, he is credited with establishing a systematic and empirical approach to the study of medicine, separating it from superstition and mystical beliefs prevalent at the time. Hippocrates emphasized the importance of observation, diagnosis, and ethical practice, principles that remain foundational in modern medicine. He is also associated with the Hippocratic Corpus, a collection of texts that laid the groundwork for medical ethics and doctor-patient relationships. His legacy endures in the Hippocratic Oath, which serves as an ethical guide for physicians even today.
