Though the Chameleon, unlike the phœnix, the griffin, or the basilisk, is a living verity, so large a body of fable has grown up around it that the animal is almost as mythical as those creatures of the imagination. The name is derived from two Greek words signifying “ground-lion,” a name singularly inappropriate in every way, as it has nothing leonine in look or nature, while its organisation fits it especially for living on trees. When we consider the singularity of its appearance and the peculiarity of its habits, it is by no means surprising that it should have attracted attention; and when we recall the numerous erroneous beliefs current amongst our rustics in England in this nineteenth century in the matter of frogs, newts, slow-worms, and the like, we can hardly wonder at the superstitions that have surrounded it. The eyes of the creature are quite expressionless, and are worked perfectly independently of each other, so that one may be directed upwards and the other downwards at the same time, or turned simultaneously to front and rear. Its exceeding slowness of movement is another curious feature, and though this exposes them to easy capture when seen, for “un Caméléon aperçu est un Caméléon perdu,” it has its advantages in another direction, for a creature that takes some hours to advance a yard or so will certainly not attract attention by any sudden movement; and the assimilation in colour of its skin with the surrounding foliage is another great protection. The creature has a singular habit of puffing out its body until it is nearly as large again, and in this state it will sometimes remain for hours. The best known fact, however, is its capacity for changing colour, passing from green to violet, blue, or yellow; but this power of varying the tint has been greatly exaggerated. We have been told that if the creature be placed on any colour, as bright scarlet, it will assume that colour; but this is one of those fragments of unnatural history that will not bear putting to the test. The following lines of Prior convey aptly enough this popular but erroneous notion:—
“As the chameleon, who is known
To have no colours of its own,
But borrows from his neighbour’s hue
His white or black, his green or blue.”
Aristotle was acquainted with the singular motions of the eyes of the creature, and his description may well have been taken from nature. At the same time, these old writers knew nothing of comparative anatomy or dissection and conducted no scientific post-mortem examinations; hence in all matters of internal structure they are often ludicrously in error, while the weakness of their statements is only perhaps equalled by the strength with which they are asserted. We are, therefore, not surprised to read in Aristotle that the chameleon has no blood except in its head. Pliny re-states all the errors made by Aristotle, and further adds that it lives without either eating or drinking, deriving its nourishment wholly from the air, and that, though ordinarily harmless, it becomes terrible during the greatest summer heats. Even Pliny, however, could not believe everything that was told him, though his powers of imbibing outrageous notions were of the keenest, and whenever any old writers deal with something more than usually incredible they fortify their statement and evade personal responsibility by adding “as Plinie saith.” Pliny, then, rejects the still older idea that its right leg artfully cooked with certain herbs conveys the power of invisibility on the eater, and will not believe that the thigh of its left leg boiled in sow’s milk will induce gout in any one so injudicious as to bathe their feet in this peculiar broth. Neither will he credit that a man may be made to incur the hatred of all his fellow-citizens by having his gate-posts anointed with another nasty preparation of chameleon. As a set-off to all this very unusual incredulity he hastens to adopt the statement of another wise man, Democritus, that it has the power of attracting to the earth birds of prey, so that they in turn become the prey of other animals—a most unselfish proceeding on the part of the creature, as its own food consists of flies and such like small matters. Democritus also asserts, and Pliny confirms him in the assertion, that if the head and neck of the chameleon be burned on oak charcoal it will cause thunder and heavy rain. One is lost in astonishment at the fertility of the imagination in these old naturalists; and though it is now easy when one has once been put on the track of discovery to surmise that the tail of a chameleon burnt on walnut charcoal might produce snow or possibly fog, much of the credit of the discovery should go to the man who first gave the clue to these physiologico-meteorological influences. Aldrovandus, another man of science gifted with a strong imagination and the power of assimilating the fancies of others, informs us that if a viper passes beneath a tree in the branches of which a chameleon is resting, the latter will eject from its mouth a poisonous secretion that effectually rids the world of the equally venomous snake; and he further adds that elephants sometimes unknowingly eat a chameleon in the midst of the foliage on which they are browsing, a mishap that is rapidly fatal to them unless they can at once have recourse to the wild olive-tree as a remedy and antidote.
Many other strange beasts might engage our attention were it not that we have much new ground yet to explore, for not only might we discourse of the strange beliefs that have clustered round these monsters, but of the equally strange fancies that have been associated with such familiar creatures as cats and dogs, hares and spiders, goats and mice, while in another section we must dwell on the equally unnatural fancies that have been associated with various plants. Before, however, passing to these we must refer to those strange imaginings, such as the troglodytes, centaurs, and pigmies, that owe more or less to the combination of the human with other forms—a large class that deserves a measure of attention that may well suggest the advisability of opening a new chapter for its benefit.
