Sergius Orata – famous fish breeder
Sergius Orata was an entrepreneur whom Pliny the Elder mentions several times in his work Natural History. On the basis of these mentions, some researchers concluded that Orata was the inventor of the so-called hanging baths, which were equated with the system of heating the floor and swimming pools in baths – hypocaustum. Nothing could be more wrong. Hypocaustum is a Greek invention, only slightly improved by the Romans, while Sergius Orata was a fish farmer and it was in this field that he was an innovator.
