This article aims to present an overall interpretation of a poem by Callimachus that centres on the dead Ptolemaic queen Arsinoe II. Firstly the position of the Ektheosis Arsinoes in Callimachus’ œuvre, the genre to which it belongs and its structure will be investigated. This leads to the analysis of the highly allusive character of the work (above all to Hesiod, Ibycus, Simonides and Pindar as well as to hymnic poetry). In addition, realia (the historical background) and textual difficulties arising from the fragmentary transmisson will also be treated. The appendix discusses a hitherto unnoticed testimony to the poem’s reception in the Roman epicist Ennius.
