Jefferies' book might have been an inspiration for the 'Statue of Liberty' moment in the original 1968 Planet of the Apes.
Felix later stumbles upon the upper part of Nelson's Column: 'He looked around, supposing that he might see the gleaming head and shoulders of the half-buried giant, of which he recollected he had been told. The giant was punished for some crime by being buried to the chest in the earth; fire incessantly consumed his head and played about it, yet it was not destroyed.' (p206)
This could have been taken from Shelley's poem, 'Ozymandias':
I met a traveller from an antique land
Who said: Two vast and trunkless legs of stone
Stand in the desert. Near them on the sand,
Half sunk, a shattered visage lies...
One can hear ringing in the air, the chilling inscription:
Look on my works, ye mighty, and despair!
