Phlegraean Fields at the Time of Odysseus

Phlegraean Fields, as you know, is a very interesting place not too far from Naples in Italy. It is characterized by great quantity of craters of sleeping volcanoes. 24 precisely visible from the space. This place is breathing -this "breast" goes up and down normally something about 2 cm a year. It's about the underground pressure. The phenomena has it's name: Bradyseism.

The name of this zone, Phlegraean Fields, means "burning fields". There are documents describing how was  this zone in the times when ancient Greeks visited it. They had seen literally burning zone because the volcanoes were alive at that period and there were different eruptions at the same time probably. Those eruptions had to be not so violent as the eruption of Vesuvius when it buried many Roman towns.

What the Greeks have seen at the time was, probably something like this:

The photo is of Naples some months ago. When the "Town of Science" was burned down. But, I think, the look had to be similar to the period of eruptions of the Phlegrean volcanoes.
