This is a Bohemian ruby red art glass wine bottle, paneled, with an engraved (cut, carved or etched) scene of a young Bacchus perched on top of a wine barrel pouring wine from a bottle to another seated young person. The date is circa 1890 to 1910.
The bottle is engraved all around with grave vines, leaves and clusters of grapes. The scene of young Bacchus is centered in the bottom and is executed with great detail and beauty. There is a wine bottle and wine glass sitting on a vine trunk to the left. The wine bottle, wine glass and the bottle that is being poured are totally clear glass, hard to see in the photos because the red glass from the opposite side shows through. The carving stands up from the glass, indicating there may be multiple layers of glass.
The function of this type of bottle is to decant a bottle of red wine into it so that the wine can breathe. I imagine the red wine contrasts with the color of the glass, and shows through the matted engravings and the clear glass I described with a stunning effect.
The bottle has faceted panels. Look closely at the sixth photo and do a zoom after you have enlarged it. The bottom half of the bottle has eight panels that come to a point about mid-way up the bottle. Around the middle are eight diamond shaped indentations, fitting over the tips of the bottom panels. The top half of the bottle has long panels again, with a tip pointing down into the diamond shapes. The ridges of the panels stand out on the glass.
The mouth is polished flat and beveled on the inside. The pontil is round, indented and polished smooth.
The stopper is clear crystal with eight ridged panels. I do not know if the stopper is original to the bottle. It is a perfect fit, however I've learned that glass this old may easily have a replacement stopper.
There are four small nicks on the edge of the mouth's rim, and I point to three of them in photos with yellow arrows. The bottom shows a lot of wear with numerous scratches in the glass. The stopper has a slight feeling of roughness along one edge, which might be a tiny pinprick nick. There may also be an air bubble or something inside the glass near the tip.
The bottle is 12 ¼" high to the top of the rim, and 15 1/8" high to the top of the stopper; it is 3" wide at the bottom.
The number 9 is etched into the bottom.
