Miles Unger

In “Picasso and the Painting That Shocked the World,” Miles J. Unger follows the painter’s early career, culminating in “Les Demoiselles d’Avignon.”

Miles Unger’s “Michelangelo: A Life in Six Masterpieces” dramatizes how the artist rose from a family near poverty to become “the first truly modern artist, emancipated not only from a slavish subservience to his patrons but from social norms altogether.”

In a new exhibition, aesthetic explorers document the Arctic that was.
