Came next; then Hebe's Cup, my final float

In that damp carnival, for now I term

Everything "Poems," and no longer squirm.

According to Kinbote (in VN’s novel Pale Fire, 1962, Shade’s mad commentator who imagines that he is Charles the Beloved, the last self-exiled king of Zembla), on his deathbed Conmal (the King’s uncle, Zemblan translator of Shakespeare) called his nephew “Karlik:”

Describing Shade’s murder by Gradus, Kinbote (in VN’s novel Pale Fire, 1962, Shade’s mad commentator who imagines that he is Charles the Beloved, the last self-exiled king of Zembla) compares himself to a stone king on a stone charger in the Tessera Square of Onhava (the capital of Zembla):

At the beginning of his poem John Shade (the poet in VN’s novel Pale Fire, 1962) compares himself to the shadow of the waxwing:

By the false azure in the windowpane;

Lived on, flew on, in the reflected sky. (ll. 1-4)
