Nicholas Myrepsos (or Nicolaus Myrepsus; Greek: Νικόλαος Μυρεψός; flourished c. 1240–80) was a Byzantine physician known chiefly for his compendium on medical science which is still extant.
He is probably the same physician who is mentioned by George Acropolites as being eminent in his profession, but very ignorant of natural philosophy.
[1] He was at the court of John III Doukas Vatatzes at Nicaea, when a solar eclipse took place on October 6, 1241, that shortly preceded the death of the empress Irene.
He mentions Mesue the Younger,[2] who died 1015; "Michael Angelus regalis,"[3] who is probably Michael VIII Palaiologos who began to reign 1259; "Papa Nicolaus,"[4] who seems to be Pope Nicholas III, who began to reign 1277; and "Dominus Joannes,"[5] and "Magister Johannes,"[6] who is probably Joannes Actuarius, who lived in the 13th century.
Nicholas compiled and revised Ancient Greek scripts including, but not limited to Galen, as well as writing his own compendium on medical science, named Dynameron (Δυνάμερον).
