If there were no nymphs, and you turned the page upside down, what would you see at the bottom? Mountains with vegetation (the bead curtains) similar to Beatus maps, with blue steams coming up from them, going into the green sea off in the distance on the other side.

Now turn it back around but look at it as though instead of mountains, they are the pointy bits in the shores of a Portolan chart, specifically of the western shore of the Italian Peninsula.

There does exist a ridge of mountains going down the peninsula and rivers run down them into the sea just as explained by the first perspective.

Pisa is shown as the beginning of the shoreline for the Tyrrhenian Sea. The Arno river is drawn as a tube, with Florence bigger than Pisa. East (up) of Florence are also mountains, sedimentary. I think you are right to compare the way that mountain is drawn with f86r as i think that is the geology page which explains how the different types of rock came to be over time.

Extinct volcanic mountains start around Pisa and basically make their way down along the shore to the active Vesuvius and Stromboli, and there are approximately seven prominent points along this shore. That is the second perspective. But the third one is that these are the volcanic mountains themselves. This is why these mountains are drawn more orderly than the one above Florence. Volcanic rock is more likely to be crystalline in structure.

The nymphs are huge in comparison, but it is because they are representatives of the wider communities of each area,. If they are dancing, it is a very structured dance telling their various histories. That is why some touch, because the communities they represent interact, while others only interact in that they can see each other across the bay.

The poses mean specific things, like a language of its own, describing historical aspects of each society. Depth of legs in water is related to time entrenched in the area, hands thrown back indicates past disaster, the lower the hands the longer ago. Hand on hip means much is known of the place and its history. Hands free means an independent society of which not much is known or was once lost.

Pozzuoli, or Puteoli, as the timing may be, is represented by one of the nymphs, (#5 from right, interacting with Naples, who stands upon Pompei…) and this could tie in with the similarities with the various versions of baths of Pozzuoli, especially since this is an extremely active volcanic area, which seems to be a highlighted feature of the geology and hydrology, so what better way to ‘link’ to more information than to reference these works.

In the third perspective with the mountains standing for the volcanoes themselves, It starts to become clear that the streams are not rivers, but extensions or representations of each volcano, and perhaps the underground effects. Naples has her arm around hers to the left, Vesuvius. Rome touches hers, off a little farther to her left, Alban Hills. The next one up is Monte Sabatini, which created Lake Bracchiani, which is drawn on the reverse of the vms page. The one that wraps around denotes the circle of volcanos n the sea between Sicily and the toe of the boot. Each stream/nymph interaction can be linked with a volcanic area near a community.

The next pool is the western shore of the Adriatic, with the tubs standing for the delta ends of rivers, and the other nymphs are islands interacting with the mainland nymph nearby.

Just some more perspectives and viewpoints to consider.
