Nearly a century after J.U Powell’s Collectanea Alexandrina (1925) and some decades after H. Lloyd-Jones’ and P.J. Parsons’ Supplementum Hellenisticum (1983) and H. Lloyd-Jones’ related Supplementum Supplementi Hellenistici (2005), a deep revision and up-dating of the whole of fragmentary Hellenistic poetry was needed, in the light of the intervening great season of critical editions of many of those texts, of widespread research on the poetic fragments themselves and on their witnesses, of increasing bibliography, and of reassessments and new discoveries (especially papyri). A selected team of scholars expert in Hellenistic poetry and culture joined forces to achieve this ambitious goal.
