'In this pioneering and wide-ranging work, Posthuman Transformation in Ancient Mediterranean Thought, M. David Litwa connects contemporary conversations in transhumanist thought with ancient philosophical traditions of angelification (alternatively, 'daimonification'). Chief among this book's virtues is its impressive range: Litwa provides comparative analyses of authors from Greco-Roman, Jewish, Christian, and Hermetic traditions, ranging from the 8th century BCE to the 3rd century CE. Litwa's work is inclusive even of traditions too often treated as marginal (e.g., 'Gnostic' texts), providing a basis for fresh comparative insights.' Travis W. Proctor, Reading Religion
