 Hegias, as a leading figure in the school, seems to have opposed Marinus, and his pupil Isidore, on many doctrinal matters.After the death of Marinus, Isidore became the new scholarch, but he did not hold the position for very long before retiring to Alexandria.Hegias may have become the new head of the school, In any case, the school continued to be divided, and Damascius, who was a student in the school during this time, presents Hegias in a very unfavourable light in his "Life of Isidore".
