Philagrius of Epirus explained

Philagrius of Epirus (Greek, Modern (1453-);: Φιλάγριος ὁ Ηπειρώτης; 3rd century CE) was a Greek medical writer from Epirus, who lived after Galen and before Oribasius, and therefore probably in the 3rd century CE. According to the Suda^[1] he was a pupil of a physician named Naumachius, and practised his profession chiefly at Thessalonica.^[2]

Theophilus gives him the title of περιοδευτής, periodeut,^[3] which probably means a physician who travelled from place to place in the exercise of his profession. He seems to have been well known to the Arabic medical writers, by whom he is frequently quoted, and who have preserved the titles of the following of his works.^[4]

De Impetigine
De iis quae Gingivae Dentibusque accidunt.
De iis qui Medico destituuntur.
De Morborum Indiciis
De Arthritidis Morbo.
De Renum vel Vesicae Calculo.
De Hepatis Morbo.
De Morbo Colico.
De Morbo Icterico.
De Cancri Morbo.
De Morsu Canis.

The Suda says he wrote as many as 70 volumes, but of these works only a few fragments remain, which are preserved by Oribasius, Aëtius, and others. In Cyril's Lexicon^[5] he is enumerated among the most eminent physicians.
