 During his sojourn in Athens, Philodemus became attached to Zeno of Sidon, the head of the Athenian Garden. He became a lifelong devotee of Zeno, an admirer of his work collecting and studying texts of the first generation of Epicureans, as well as his mode of teaching, which is reflected in Philodmus’ treatise On Frank Criticism. He published some books on the basis of Zeno’s lectures—e.g., On Frank Criticism and On Signs— and defended Zeno’s views on, e.g., the recognition of the technical character of panegyric or ‘sophistic’ rhetoric, which he insisted was the view of the school’s founders, as well.
