German Magdalenian Planisphere in Gönnersdorf Andernach ?
There are many megalithic and prehistoric sites in Germany.
I have a possible decipherment of a stone allegedly preserved under the pumice from a volcano eruption and thus datred to ca. 11000 BC at Maria Laach near Koblenz, Germany and near the Magdalenian sites of Andernach near Koblenz and Gönnersdorf near
Neuwied (other side of the Rhine)
The decipherment is found in the file rhineman.tif at

The stone could be interpreted as a planisphere of the heavens dated to 11000 BC, at a time when the summer solstice point was at the base of the division of the
Milky Way into two legs near Aquila and Serpens Cauda. The "joining"
area of the two legs of the Milky Way is at Deneb in Cygnus.
However, this is so far and improbably back in time, that this idea should be treated as very speculative at best.
