Interesting - I did what I normally do with research; I like
  finding out opinions-of-the-day and compare with the
  opinions-based-on-opinions that we receive. I do not mean to
  imply the original is better; often the input of many more
  brains on the same object can lead to more interesting results.
  But I like knowing about things when they're fresh.

  First mention I find of the art is: "Annuaire illustr* des
  beaux-arts: revue artistique universelle", 1882-83.

  It's in French, which I can't read. It's also in some stupid
  dreaded unnecessary encrypted new Adobe PDF format via Google.

  Thankfully, Internet Archives doesn't care. It's off copyright,
  so it belongs to all of us, and they scanned it. Not the best
  OCR but enough.

  So, Ran THAT through Google translate.. .

  At this time, the focus of art critics was the style and the way
  it makes you feel. The symbolic interpretation is likely the
  product of later art critics/historians/academics, but
  initially, the impression was that of freshness and lightness.
  The difference between initial observations and subsequent
  interpretations is fascinating to me.

  and the opinion of 1882 is:

  Until proof to the contrary, it seems the point
  black coat that lends itself to aesthetic combinations
  feelings of maudlin or only serious order. This is
  probably why Mr. Manet - and after him M. de Nittis -
  Fa will never introduced in the picturesque movement
  mobs, as formerly in his Bal VOp*ra in his
  Lunch che \ Lathuille the father and today in a
  Bar at the Folies-Bergere. Those who fear like
  we silliness and insipidity which inevitably leads to
  research "subjects distinguished" in painting, are served
  wish in this last picture of Mr. Manet. It is not per-
  set to be more 'girl' that the creature installed by the artist
  behind the marble bar laden with fruit and bottles. This
  is not how we see the essential merit of his
  artwork. This merit is the right vision of things, their
  color, their light vibration, appearance
  undulating and bandwidth so fleeting, so fast. Here is the
  triumphant
  phe Mr. Manet; We do not capitalize forms, such as
  M. Beraud made in similar subjects, he catches them
  their effective mobility, and it does not keep its tables
  more stopped printing, sharper than reality
  movement. This is a very new art form, very personal
  tional, very hot, direct conquest of the artist
  world of external phenomena and which shall not be
  lost for the future.
