Aulus Cornelius Celsus
Aulus Cornelius Celsus ( 25 BC - 50 AD) was a
Roman encyclopaedist, 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.
