Medical Renaissance in the context of "Andreas Vesalius"

Paracelsus (/ˌpærəˈsɛlsəs/; German: [paʁaˈtsɛlzʊs]; c. 1493 – 24 September 1541), born Theophrastus von Hohenheim (full name Philippus Aureolus Theophrastus Bombastus von Hohenheim), was a Swiss physician, alchemist, lay theologian, and philosopher of the German Renaissance.

He was a pioneer in several aspects of the medical revolution of the Renaissance, emphasizing the value of observation in combination with received wisdom. He is credited as the "father of toxicology". Paracelsus also had a substantial influence as a prophet or diviner, his "Prognostications" being studied by Rosicrucians in the 17th century. Paracelsianism is the early modern medical movement inspired by the study of his works.

Aulus Cornelius Celsus (c. 25 BC – c. 50 AD) was a Roman encyclopedist, known for his extant medical work, De Medicina, which is believed to be the only surviving section of a much larger encyclopedia. The De Medicina is a primary source on diet, pharmacy, surgery and related fields, and it is one of the best sources concerning medical knowledge in the Roman world. The lost portions of his encyclopedia likely included volumes on agriculture, law, rhetoric, and military arts. He made contributions to the classification of human skin disorders in dermatology, such as myrmecia, and his name is often found in medical terminology regarding the skin, e.g., kerion celsi and area celsi. He is also the namesake of Paracelsus (lit. Above Celsus), a great Swiss alchemist and physician prevalent in the Medical Renaissance.
