This volume offers a clear and authoritative gateway into the world of Hellenistic poetry, presenting the state of the art in a form accessible to newcomers and valuable to experienced scholars alike. Designed for undergraduate and graduate students of ancient cultures, especially those in Classics, as well as instructors and researchers, it distils a complex literary era into an illuminating, concise guide. Moving beyond isolated readings of individual poets such as Callimachus, Theocritus and Apollonius, the book situates Hellenistic poetry within its rich historical, political, cultural, and religious contexts, and discusses its important afterlife in Roman poetry. It highlights how shifting power structures, expanding intellectual networks, and new forms of cultural expression and religion shaped poetic innovation both in Alexandria and in the wider Mediterranean world. Whether used in the classroom or consulted as a research companion, this Companion provides an indispensable, overview of a transformative period in ancient literature.
