Paul of Aegina or Paulus Aegineta (Greek: Παῦλος Αἰγινήτης; Aegina, c. 625 – c. 690) was a 7th-century Byzantine Greek physician best known for writing the medical encyclopedia Medical Compendium in Seven Books. For many years in the Byzantine Empire, this work contained the sum of all Western medical knowledge and was unrivaled in its accuracy and completeness.
Nothing is known about his life, except that he was born in the island of Aegina, and that he travelled a good deal, visiting, among other places, Alexandria. He is sometimes called Iatrosophistes and Periodeutes, a word which probably means a physician who travelled from place to place in the exercise of his profession. The exact time when he lived is not known; but, as he quotes Alexander of Tralles, and is himself quoted by Yahya ibn Sarafyun (Serapion the Elder), it is probable that Abu-al-Faraj is correct in placing him in the latter half of the 7th century.
The Suda says he wrote several medical works, of which the principal one is still extant, with no exact title, but is commonly called Medical Compendium in Seven Books (Greek: Επιτομής Ιατρικής βιβλία επτά, Epitomes iatrikes biblio hepta). (Digital German edition by the University and State Library Düsseldorf) This work is chiefly a compilation from earlier writers; indeed its Greek title proclaims that it is an epitome of medicine, "epitomes iatrikes."
