Callimachus was one of the most important and influential writers in the ancient world. He was the outstanding poet of the Hellenistic period, and had a profound effect on the subsequent course of Greek and Roman literature. The hymns are intricate, allusive and difficult poetry, and need elucidation for the modern reader. The Fifth Hymn, The Bath of Pallas, is considered by many to be Callimachus' finest surviving poem. Anthony Bulloch has established a new text of the poem, which is printed here with facing English translation. The substantial introduction and full commentary aim to introduce the poem to a wide audience and to help the modern reader to reconstruct what the ancient reader may have taken for granted as part of the crucial and intellectual background and to achieve an informed and sensitive appreciation of the poem in its full perspective. This is the first full edition of and commentary on the work in English. It will be welcomed by Greek scholars and those interested in Greek and Roman poetry.
