One of his generation's most popular artists, German Romantic painter Caspar David Friedrich is known for his allegorical landscapes that convey a deep sense of contemplation and melancholy. 2024 marks the 250th anniversary of the birth of this outstanding artist, whose paintings continue to gain in topicality - hardly a discussion on climate change without one of his iconic paintings, such as The Sea of Ice, being invoked as a silent witness. Barbara Hess examines the painter's work and his life, from its lasting poignancy to the great themes of Romanticism and drawing. In the playful format of an A-Z book, the author takes us on a timely journey, showing how new views and perspectives can be gained from what has long been thought familiar.
