The Shelleys passed the Drance during their Swiss excursion; it is described in Letter
6 of A History of a Six Weeks' Tour:
As soon as we had passed the opposite promontory, we saw the river Drance, which descends
from between a chasm in the mountains, and makes a plain near the lake, intersected
by its divided streams. Thousands of besolets, beautiful water-birds, like sea-gulls,
but smaller, with purple on their backs, take their station on the shallows, where
its waters mingle with the lake.
