The Hellenistic period, spanning from Alexander the Great's death to Rome's conquest of Egypt, saw Greek culture spread across the Mediterranean and Near East. This era witnessed literary innovation, scientific advancement, and the rise of new philosophical schools like Stoicism and Epicureanism. Key figures like Callimachus and Theocritus revolutionized poetry, while Menander's New Comedy influenced later Roman drama. The period's cosmopolitan nature fostered cultural exchange, leading to syncretic religious practices and the blending of Greek and non-Greek traditions in art and literature.
