Metamorphoses of Light
‘Goethe called colour the deeds and sufferings of the light – victorious deeds when it pierces matter, and suffering when it endures the darkness in matter.

Observers of the Aurora Borealis in Europe

This book is dedicated to some of the main aurora observers in Europe and to the human, institutional and philosophical context in which they evolved in the first half of the 18th century. Its reading should be seen as a retrospective journey through the scholarly world of the Enlightenment, during which the same scholars are frequently encountered and reencountered, yet each time in different contexts, or from different angles, with the aim of compiling an account of the swarming of ideas and encounters that constituted the development of experimental science in this pivotal period.
