On the face of it, the reviewed work is yet another collection of essays (and responses) derived from the papers presented by their respective authors at the 2018 conference Celsus in his World, organized by the Centre for Research in the Arts, Social Sciences and Humanities at the University of Cambridge. Upon closer inspection, however, the volume successfully avoids the usual pitfalls of such undertakings and its individual contributors together with the editors, James Carleton Paget and Simon Gathercole, are to be congratulated for producing one of the best comprehensive volumes on Celsus in recent memory. The collected essays are preceded by a helpful Introduction, in which the editors set the stage by providing an overview of principal issues related to Celsus’ work (title, purpose, text, date, provenance, sources) as well as outlining his intellectual background, esp. his relation to and knowledge of Greek philosophical tradition, Christianity and Judaism.
