A finely crafted interdisciplinary study, that throws light on the intellectual atmosphere of eighteenth century France by investigating the pervasive influence of François Fénelon's novel Télémaque (1699) on literature, the visual arts, and opera, pertinently for this book on the librettos of Mitridate and Idomeneo. The author's extensive exploration of Telemacomania, largely unknown in opera studies, goes far in elucidating aspects of both Mozart operas, particularly Idomeneo.
