The Atlas of Petromodernity is many things in one: historical and geographical non-fiction, cultural theory essay, and picture book. In forty-four short essays, inspired by an equal amount of pictorial findings, Klose and Steininger develop a technical, geographical, political, and speculative panorama of the declining era of petroleum modernity. The authors stroll through Baku, Rotterdam, and Louisiana, into Manchuria and through the Vienna Basin. They read Bertolt Brecht, technical manuals, and petroculture theory, and they listen to Neil Young. They go to the moon, through refineries and over highways emptied by the COVID-19 pandemic. They confront petrochemistry with petromelancholy, catalysis with catharsis, cosmos with cosmetics. The Atlas of Premodernity tackles the contradictory ambivalences of a substance that has been vital for our epoch, and whose roles and meanings need to be understood in order to be able to leave this epoch behind.
