The final chapter of John Wyndham's The Midwich Cuckoos is entitled "Zellaby of Macedon". Did he ever give any reason for this choice of title? Off the top of my head I can see no obvious connection with the old Kingdom of Macedon,or of its most eminent son, Alexander the Great. Can anyone provide or think of a reason for it?
I would guess that this refers to the legend of the Gordian Knot, in which Alexander "The Great" of Macedon "solved" the problem of untying a complicated knot by simply cutting it. In The Midwich Cuckoos the problem of the Cuckoos is solved in a similarly dramatic fashion by the philosopher Zellaby.
