What is "aegimus"

Aegimus or Aegimius ( or ) was one of the most ancient of the Greek physicians, who is said by Galen to have been the first person who wrote a treatise on the pulse. He was a native of Velia in Lucania, and is supposed to have lived before the time of Hippocrates, that is, in the 5th century BC. His work was entitled ( Lat. De Palpitationibus, a name which alone sufficiently indicates its antiquity), which is no longer extant.

Athenaeus (2nd century a.d.) mentions that Callimachus (3rd century b.c.) used to have a work by "Aegimius" that described the art of making cheesecakes , and Pliny the Elder mentions a person of the same name who was said to have lived two hundred years; but whether these are the same or different individuals is quite uncertain.
