In Canto One of his poem John Shade (the poet in VN's novel Pale Fire, 1962) speaks of his dead parents and mentions a preterist (one who collects cold nests):
I was an infant when my parents died.
They both were ornithologists. I've tried
So often to evoke them that today
I have a thousand parents. Sadly they
Dissolve in their own virtues and recede,
But certain words, chance words I hear or read,
Such as "bad heart" always to him refer,
And "cancer of the pancreas" to her.
A preterist: one who collects cold nests. (ll. 71-79)
