In The Hobbit while describing Lake Town the following intrigued me:
The rotting piles of a greater town could still be seen along the shores when the waters sank in a drought.
A lot of such references in the Hobbit are alluding to things mentioned in other works. Is there anything like this for the previous lake town?
From what I have read is Esgaroth prior to the dragon was built on the shore not on the lake itself. The quote above would seem to refer to another town built on the lake.
