amphisbaena

The Amphisbaena, “goes both ways”, is one of the many snakes encountered by Lucan and his army in the deserts of Libya. It has also been reported from Lemnus, but it is unknown to the Germans. Unlike its biological namesake, the harmless burrowing lizards known as amphisbaenas, the Libyan amphisbaena is venomous and deadly, producing double the amount of venom a regular snake would.

Two heads are an amphisbaena’s distinguishing feature, with one head in the normal place and one at the end of the tail. How these heads affect locomotion is unclear. An amphisbaena may move like a regular snake, one head trailing behind, but changing directions instantly and going forward or backwards with equal ease. Alternatively, both heads could lead, leaving the body following behind in a loop. An amphisbaena’s sight is poor, but its eyes glow. Physically it resembles an earthworm, with an indistinguishable head and tail. It is blackish earth-colored, with a rough, spotted skin.

In addition to the amphisbaena described above, Pammenes tells of two-headed snakes with two feet near the tail in Egypt. Borges reports a creature from the Antilles called the doble andadora (“goes both ways”), also known as the two-headed snake and the mother of ants. It feeds on ants and can reattach itself if chopped in half. However, there is little outside of Borges’ account to corroborate it. The medieval amphisbaena became a two-headed dragon, in a wide variety of forms. Any creature in medieval art with an extra head on the end of its tail can be safely labeled an amphisbaena, although at this point the Greek two-headed snake is long forgotten.

Amphisbaenas are very cold-resistant, and are the first snakes to come out after winter, ahead of the first cuckoo song. Their temperament is correspondingly hotter than that of other snakes. Solinus believed amphisbaenas gave birth through the tail-end mouth. They take good care of their eggs, guarding them until they hatch and showing love to their offspring.

Amphisbaena venom is unremarkable and causes the same symptoms as viper bites – inflammation and slow, painful death. Besides drinking coriander, the antidotes for amphisbaena bite are the same as those used for vipers. Amphisbaenas themselves are hard to kill, except with a vine-branch. One amphisbaena woke Dionysus from his rest, and in retaliation he crushed it with a vine-branch.

Several remedies have been derived from amphisbaenas. A walking-stick covered with amphisbaena skin keeps away venomous animals, and an olive branch wrapped in amphisbaena skin cures cold shiverings. An amphisbaena attached to a tree will ensure that the logger will not get cold and the tree will fall easily. If a pregnant woman steps over a dead amphisbaena, she will abort instantly, as the vapor arising from the dead snake is so toxic as to suffocate the fetus. However, if a pregnant woman carries a live amphisbaena in a box with her, the effect is nullified.

The two heads of the amphisbaena understandably led to a healthy amount of criticism. Thomas Browne denied that amphisbaenas could exist, stating that an animal with two anteriors was impossible. Al-Jahiz recounts an interview with a man who swore that he saw an amphisbaena, and, unconvinced, chalked it up to fear-induced exaggeration. “From which end does it move?” he asked the man. “Where does it eat from, and where does it bite from?” The man replied “It doesn’t move forward, but it gets around by rolling, like boys roll on sand. As for eating, it eats lunch with one head and dinner with the other. And as for biting, it bites with both heads at the same time!”
