What Does It Mean to be "Natural?"
However, not all monsters were monstrous births witnessed by physicians. Ambroise Paré (1510?-1590) also tells of monstrous animals, some of which are familiar to us today (the rhinoceros) and many of which are not. The early modern period, when many texts with woodcuts of monsters were circulated, such as Paré's, was also an intense time of global exploration. This meant that “nature” was expanding dramatically. Ships arriving to the New World of Africa brought back animals, plants, and people that defied easy belief. As a modern reader looking back at early texts with their unbelievable woodcuts of monsters, we must try to imagine what it must have been like during this time of exploration and discovery.
Were monsters truly “outside of nature?”
Most physicians did not think so. They believed that monsters were important messages from God, but they also believed that God was working through the laws of nature to produce these "mira." Not miracles, but mira— wonders. But physicians did not yet have a clear understanding of how humans developed in the womb. They could not say for certain what natural laws God was working through. Were monsters natural or unnatural? This was a challenging question to answer when no one understood what the “natural” course of gestation was. The answers to these questions were greatly aided by the development of anatomical preservations in 18th century medical museums. Physicians could preserve fetuses at various stages of development and, through observation, determine the natural laws of human development.
