Note: Many medical terms used in the past – even through the first half of the 20th century – are words that we find insensitive or cruel today. Like any field of history, it is important to keep in mind the time period in which the texts were written and to not pin our 21st-century beliefs on those of the past. As historians, it is up to us to observe, not to judge.
At one time, the word “monster” was used to describe people with medical anomalies, not just fabulous creatures out of legends. The fascination with so-called “monsters” dates back at least to antiquity. Aristotle (384 – 322 BC), a Greek philosopher and scientist; Pliny the Elder (AD 23 – August 25, AD 79), a Roman philosopher; and Saint Augustine of Hippo (13 November 354 – 28 August 430), an early Christian theologian and philosopher, all discuss the monstrous in their works.
In the second half of the 15th century, the printing press helped spread knowledge like never before, and books on monsters became more popular. Some monsters are animals that we know today, although they may not recognizable. Ambroise Paré’s (1510-1590) Les oeuvres d’Ambroise Paré includes an astonishing number of monsters, both animal and human, real and legendary. In his book he recorded creatures like seahorses, crocodiles, and unicorns, along with conjoined twins, men born without limbs, and strange human-animal hybrids. It was believed that the birth of these monsters and “prodigies” often foretold an impending disaster.
In 1605, female conjoined twins were born in Paris. The story of the twins was published at least four times, and this was the first attempt at explaining a monstrous birth with scientific reasoning, rather than superstition. It was during the 17th century that curiosity began to replace the suspicion with which monsters were perceived. Scholars were more inclined to use reason in an attempt to explain the world around them.
This new, scientific attitude to the world continued throughout the 18th century. The 18th century saw the formation of numerous scholarly societies, which in turn led to more detailed medical studies of monstrous births and other anomalies. It was during the early 19th century when Isidore Geoffrey St. Hilaire coined the term teratology (the study of abnormalities of physiological development). As medical knowledge continued to grow and monstrous births were studied with a more scientific attitude, the attitude towards the “monsters” themselves also changed. Once seen as creatures to be feared, people born with physical anomalies were, for the most part, seen as opportunities for the field of medicine to advance.
Even with the move to a more logical, scientific search for knowledge, it wasn’t until the early 20th century that the word “monster” stopped being used to describe people born with physical abnormalities. It was even later – during the second half of the 20th century – when carnivals stopped exhibiting “freaks” as sideshows. Today, of course, the words “monster” and “freak” are not used to describe people with medical anomalies, but that wasn’t the case in fairly recent history.
