This early description of the amphisbaena depicts a venomous, dual-headed snakelike creature. However, Medieval and later drawings often show it with two or more scaled feet, particularly chicken feet, and feathered wings. Some even depict it as a horned, dragon-like creature with a serpent-headed tail and small, round ears, 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." Nicander's account seems to be referring to what is indeed called the Amphisbaenia.
In ancient times, the supposedly dangerous amphisbaena had many uses in the art of folk medicine and other such remedies. It is said that expecting women wearing a live amphisbaena around their necks would have safe pregnancies; however, if one's goal is to cure ailments such as arthritis or the common cold, one should wear only its skin. By eating the meat of the amphisbaena, one could attract many lovers of the opposite sex, and slaying one during the full moon could give power to one who is pure of heart and mind. Lumberjacks suffering from cold weather on the job could nail its carcass or skin to a tree to keep warm, while in the process allowing the tree to be felled more easily.
