In the 19th century, it was very common to attend astronomy performances. In an age of immense scientific progress, the planetarium was a refuge for both fact and fiction. This mingling of the heavenly and earthly produced cosmological narratives that made sense of the position of humankind and technology in a rapidly evolving world. Fast forward to 2019. Pieter De Buysser’s tale begins in Argentina while giving a lecture on the writer Letizia Álvarez de Toledo. High time to reinstate the astronomy performance! And where better place than at the Brussels Planetarium?
