„As they raced along to the gate out of which the elephant had vanished, Syme felt a glaring panorama of the strange animals in the cages which they passed. Afterwards he thought it queer that he should have seen them so clearly. He remembered especially seeing pelicans, with their preposterous, pendant throats. He wondered why the pelican was the symbol of charity, except it was that it wanted a good deal of charity to admire a pelican. He remembered a hornbill, which was simply a huge yellow beak with a small bird tied on behind it. The whole gave him a sensation, the vividness of which he could not explain, that Nature was always making quite mysterious jokes. Sunday had told them that they would understand him when they had understood the stars. He wondered whether even the archangels understood the hornbill.“ (Chesterton, The Man Who Was Thursday)
