On [:] Captive | Charlotte Brontë, 1847

Frederick Carl Frieseke, Bird in a Cage, 1937

“I see at intervals the glance of a curious sort of bird through the close set bars of a cage: a vivid, restless, resolute captive is there; were it but free, it would soar cloud-high.”

Charlotte Brontë, Jane Eyre, 1847
