A Greek hymn is selected among other examples in the corpus of Greek ‘magical’ papyri written in Egypt during the Roman Imperial time. Addressed to the Moon goddess in a plurality of forms and names, it draws a complex portrait of a powerful divinity for love affairs. The incantation weaves innovative denominations together with a poetic and ritual tradition in order to enact power. The poet realised a technical ‘tour de main’ to picture a many-faced goddess, tying heavenly and shining traits to the gloomiest and the deadliest, and entangling anthropomorphic characteristics to a patchwork of animal features. The poetic mastery over names and figures offers tools for the making of the divine inside the ritual performance, with the effect of rendering a vivid perception of the Moon goddess encompassing all her aspects.

The Introduction familiarises the reader with Galen, his life and work, and offers essential information on his engagement with ethical philosophical writings. It also provides a brief introduction to practical ethics in antiquity, and foregrounds the contribution of the present study and the methodology through which the study will explore the topic under investigation. Finally, the Introduction gives an overview of the main chapters of the book.
