In Canto Two (begun "early in the morning" on July 5, 1959) of his poem John Shade (the poet in VN's novel Pale Fire, 1962) says "Today I'm sixty-one:"
And finally there was the sleepless night
When I decided to explore and fight
The foul, the inadmissible abyss,
Devoting all my twisted life to this
One task. Today I'm sixty-one. Waxwings
Are berry-pecking. A cicada sings. (ll. 177-182)
