Is it salt water, so it's sea water?
There are springs in the Alps where since the Celts and Romans are known.
Salt water comes directly from the mountain. Some of it smells like rotten eggs. Some have a temperature of 40 degrees.
A famous salt spring is in the south of France near the Pyrenees, near the Spanish border.
Salt does not necessarily mean sea.

I said sea because of its size in comparison to the tube rivers, the tubes mean to me navigable rivers, those on which large ships can sail, so it is not likely to be a pond or a lake, per se, if given that context of size. Specifically, I see it as the Persian Gulf because of the two rivers becoming one and flowing into it, plus some other hints, like when i arrange my pages the previous is Lake Sevan (fresh water) and Lake Urmia (salt water),  and this is near where the Euphrates and Tigris rivers rise. The page after (other side of folio) is west India (Gujurat) which gulfs are the first bodies of water next along the eastern shore from the Persian Gulf, and then turning across to the Red Sea, directly across. It all flows, it follows the path of the water bodies. After that it speaks of the ancient canal to the Nile.

The springs in the Alps are also depicted in green on another page but in a different way. There is also a sulphur spring on the previous page to that one shown in yellow, depicted near a lake (in blue) in the shape of Garda, and there is one there irl (i assume the sulphur is the rotten egg smell you speak of).

So the tube in the Persian Gulf speaks to me of the previous state of the water body, i.e. how it came to be. The sea was not always there, it was many believe that the Garden if Eden might have existed in a place currently under water, or that used to be under water. This can be seen today in the depth of the gulf in comparison to the Oman sea, the previous river shows as the trench. 



This occurs on the next Red Sea page also, with the fish standing in for the trench there, from when there was a river system where the nymph stands on the Arabian coast. The water spray on her hand in the drawing can be seen in the landscape as erosion from an extinct river. Her hand is now volcanoes irl. 

Imagine a time during the last ice age, how this would be a pocket of livable space, with warmth due to volcanic activity. It seems perfectly plausible that this was one of the first places inhabited when humans migrated out of Africa, and falls in line nicely with the Anaximander fish mouth evolution idea.
