Segments from illustrations
[left]: by Gustave Doré (to John Milton's Paradise Lost, Book VI, 1866) and
[right]: by Henry Holiday (to The Hunting of the Snark, 1876) .

Here Henry Holiday played with zoomorphism and turned what could be parts of a root into a (naughty) winged rat.

i am not sure whether Doré's hatching of the "nose" and the "paw" is part of a joke already by Doré in that otherwise quite hellish scenario.
