Theophrastus succeeded Aristotle as teacher of the Lyceum when Aristotle left Athens at the death of Alexander the Great. He probably continued Aristotle's work in areas including botany, zoology, rhetoric, and modal logic. Menander is said to have been one of his disciples.
Few of the writings of Theophrastus survive. He is known for his personality traits or Characters. Some of the traits described in the Characters of Theophrastus are: flattery, complaisance, surliness, arrogance, irony, boastfulness, petty ambition, late learning, unreasonableness, officiousness, and unpleasantness.
