Amphisbaena (plural: amphisbaenae) also called the Mother of Ants, is a mythological, ant-eating serpent with a head at each end.

Amphisbaena, the twin serpents


Amphisbaena' is a Greek word, from amfis, meaning bothways, and bainein, meaning to go.

Also called Amphisbaina, Amphisbene, Amphisboena, Amphisbona, Amphista, Amphivena, or Anphivena (the last two being feminine),


According to Greek mythology, the mythological amphisbaena was spawned from the blood that dripped from Medusa the Gorgon's head as Perseus flew over the Libyan Desert with it in his hand.

Cato's army then encountered it along with other serpents on the march. Amphisbaenae fed off of the corpses left behind.


The earlier descriptions of the amphisbaena depict what looks basically like a snake (perhaps an Indian Sand Boa), but with a head at either end. However, medieval and later drawings often show it with two or more scaled feet, particularly chicken feet and feathered wings. Some even depict it with horns on the front head and small, round ears on the other, or horns on both heads.

These horns are long and either curved upwards or slightly spiraled. Also, some show it with the second head on the end of its tail, while others have both "necks" of equal size so that it cannot be determined which is the rear head.

Many descriptions of the amphisbaena say its eyes glow like candles or lightning, but the poet Nicander seems to contradict this by describing it as "always dull of eye". He also says: "From either end protrudes a blunt chin; each is far from each other."

Pliny:" the amphisbaena has a twin head, that is one at the tail end as well, as though it were not enough for poison to be poured out of one mouth."
Sir Thomas Browne: " a smaller kind of Serpent, which moveth forward and backward, hath two heads...Which double formations do often happen unto multiparous generations, more especially that of Serpents; whose productions being numerous, and their Eggs in chains or links together (which sometime conjoyn and inoculate into each other) they may unite into various shapes and come out in mixed formations." (Pseudodoxia Epidemica)


  • regenerative abilities - if the amphisbaena is cut in half, the two parts can rejoin
  • venomous fangs - the amphisbaena is venomous, as Pliny the Elder indicates: "The amphisbaena has a twin head, that is one at the tail end as well, as though it were not enough for poison to be poured out of one mouth."
  • efficient duplicity - the amphisbaena's heads can handle more than one task at once.
  • speed - according to some accounts, the amphisbaena can slither (or run) very quickly, and, in the case of the limbless amphisbaena, it can slither in either direction, as Isidore of Seville indicates: "It can move in the direction of either head with a circular motion." The poet Nicander, however, describes the amphisbaena as "slow in motion".
  • rolling - by locking the jaws of its two heads or holding the neck of one in the mouth of the other, the amphisbaena can roll like a hoop, as depicted by medieval artists
  • warmbloodedness - unlike most serpents, the amphisbaena was apparently unperturbed by the cold, as Isidore of Seville indicates: "Alone among snakes, the amphisbaena goes out in the cold."


  • pregnancy - pregnant women wearing an amphisbaena around their necks would supposedly have safe pregnancies; in accord with this, women in power would wear bracelets in the shape of amphisbaenae
  • arthritis - wearing a dead amphisbaena or its skin would cure arthritis
  • chilblains - wearing the skin of an amphisbaena will reduce this swelling of the hands caused by cold
  • cold - wearing a dead amphisbaena or its skin is a cure for a cold
  • woodcutting - nailing the skin of an amphisbeana to a tree before cutting it down will make it easier to fell the tree and keep the lumberjack warm

References in heraldry

As well as a legendary creature referenced by ancient historians and a monster from Greek mythology, the amphisbaena is a heraldic creature.

Amphibanes, or Amphibenes is a heraldic term indicating the crest: "on a Saltire or, interlaced by two Amphisbaenae azure langued gules a rose of the last barbed and seeded purpure". This was the crest of Gwilt.

In plain English, this means a rose with purple thorns and seeds interlaced by two blue, red-tongued amphisbaenae, with a yellow X in the background.


The amphisbaena has been referred to by the poets, such as Nicander, John Milton, Alexander Pope, and Lord Tennyson and the amphisbaena as a mythological and legendary creature has been referenced by Lucan, Pliny the Elder, Isidore of Seville, Sir Thomas Browne, the last of which debunked its existence.


There are 158 different species of worm lizards in the zoological suborder Amphisbaenia. One of these species is probably the origin of this legend. An excellent herpetological resource is the EMBL Reptile Database, which has all of the different species listed and pictures. [[1]]
