"Awakening the Night: Art From Romanticism to the Present" at the Belvedere Museum in Vienna includes 300 works interpreting the night - as the realm of darkness, a safe haven or a reflection of oneself, from Romanticism to 21st-century art. The Romantic era was a period when, in literature and visual arts, the perception of the night was redefined under the influence of sciences like astronomy and psychology. On display are paintings, prints, drawings, photographs, films, sculptures and objects by Friedrich, Waldmüller, Nolde, Kirchner, Magritte, Delvaux and Ansel Adams. Through Feb. 17.
