All I've heard is the big objects look like the Sun and Moon or full Moon and Moon. The cluster might be the Pleiades. What the swish is is a good question. The Milky Way or a Solar or Lunar arc?
I guess Pleides too. Sirius should be there somewhere.
Maybe the swish is the Orian belt. I will look into this more.
Another link mentioned this was found within a circular wall that was used for astronomical observations. The semicircular region on the edge might be a paticular part of the wall, maybe toward the east.
The cluster of 7 stars could be the 7 sisters of the Pleidies.
To the left and upward of these looks like the W of Cassiopiea.
On the left edge you see a double star. This maybe the double star of the big dipper handle that is visible with acute naked eyes.
I don’t have guesses for the rest.
