The fifteenth volume of lectures from the Warburg House brings together contributions whose spectrum of content ranges from the dispute over the dome of St. Peter's Basilica in Rome in the mid-18th century to Aby Warburg's scientific and popular educational commitment to the Hamburg Planetarium and the aesthetic treatment of machine and technology. With contributions by Pascal Dubourg Glatigny, Emmanuel Alloa, Alexander Honold, Birgit Recki, and Gertrud Koch.
