So I came across a sentence while reading the book On The Map:
His[Eratosthenes’] world map was drawn in about 194 BC. No contemporary version exists, but the cartographer’s descriptions were interpreted for a Victorian audience, and this remains the generally accepted and widely used reproduction.
It really makes me wonder what does "a Victorian audience" mean. If the map was drawn in about 200 years BC, how could it be firstly interpreted only during the Victorian era, some 2000 years later? What does "a Victorian audience" here really mean?
