" [Touching his own breast.] In here, you see—in here I have a little bramah-locked casket. And in that casket all my sculptor's visions are stored up. But when she disappeared and left no trace, the lock of the casket snapped to. And she had the key—and she took it away with her.—You, little Maia, you had no key; so all that the casket contains must lie unused. And the years pass! And I have no means of getting at the treasure. "

― Henrik Ibsen , When We Dead Awaken
