Some ancient collections of animals were very large and contained a wide variety of species, although specific details of these collections were not recorded. Many cultures such as the Chinese, Egyptians, Persians, Greeks, Arabian, and India collected. Little is known about how or where they kept these animals, or even what the animals were. Our knowledge comes from when these animals appeared in the processionals (parades) or in the arena fights. However, there is proof that large elephant exhibits were maintained outside of Rome. There is also proof of people who cared for the sick animals (veterinarians).
