During the Middle Ages and even several
centuries later, explorers and travellers to exotic far-flung localities around
the globe would often return home to Europe with unusual animal specimens as
interesting souvenirs. Sadly, however, some of these items were outright fakes
(such as the infamous 'Feejee mermaids', which were composite creations deftly
manufactured from preserved monkeys and large fishes) or deliberately
misidentified objects (such as ibex or antelope horns masquerading as griffin
or dragon claws) that had been sold to the unsuspecting voyagers at exorbitant
prices by unscrupulous vendors.
An ophidian representative from these shaming
cabinets of credulities was the unicorn snake. Generally procured in the East, this usually took the form of a
dried, preserved serpent of fairly sizeable proportions but sporting as its
most eyecatching characteristic a long spine protruding from the centre of its
brow like a veritable herpetological unicorn.

Needless to say, however, an examination of
such a specimen by an experienced naturalist invariably revealed that its
'horn' was merely a cut-down quill from a porcupine or a spine from a hedgehog or spiny-finned fish that had been carefully inserted and glued inside the
serpent's head. I have also read of living specimens of supposed unicorn
snakes, though I can't imagine that any snake would live very long if they had
been subjected to such a barbaric treatment, because the inserted quill or spine would probably pierce their brain.
Worth noting is that there is a real species
of snake that is sometimes dubbed the green unicorn. More commonly termed the
rhinoceros rat snake Rhynchophis boulengeri, however, this green-scaled non-venomous
colubrid from Vietnam and China earns its rhino and unicorn epithets from the
very prominent, pointed, scaly protrusion borne upon the front of its snout
like a small horn.
