At the end of Canto Three of his poem John Shade (the poet in VN’s novel Pale Fire, 1962) mentions a Balkan king and some faint hope:
Yes! It sufficed that I in life could find
Some kind of link-and-bobolink, some kind
Of correlated pattern in the game,
Plexed artistry, and something of the same
Pleasure in it as they who played it found.
