When
an interest was increasing for Volcanology and geology, the Solfatara, much
easier to reach than Vesuvius or Etna, became the destination of numerous
travellers and scholars, inventing in this way a complex Phlegraean itinery,
which, when followed
made it
possible to admire and learn about the subsoil, countryside and
archaeology.
