Very old clock

This old clock has also been passed down in our family. It has three parts. The clock itself and two candle candelabres Socles are made of a beautiful stone with metal legs. The wind up clock movement works perfectly. One of the candle candelabre has a separated candle holder. It suddenly came apart (made of heavy brass) and you can see where a black string is holding it together. I do not know what to do to fix this separation between the two pieces of brass. The statue is beautiful but I do not know who she represents if anyone at all.

I look forward to your expert advice on this as I do not know it's age, type of stone used or who made it. I would sure love to know.
Thank you for looking and for responding. I am amazed at some of the things I am finding out, especially with the medals.

Note added: As always, my trusted friend and expert wrote to me from Germany to provide me with more details on this beautiful clock. Here is what Mr. Bauer wrote:

"hallo,
This beautiful clock is a French Pendule / Mantel Clock / Figurenuhr. The movement works for about a week. It is always signaled the half hour and full hour with a fine bell. (perhaps a quarter of an hour?).

The dial is enamel. Please carefully, it can quickly be cracked! The case is a red marble.
There is a whole part of marble. It is finely ground and polished. The feet, the bezel and the figure is bronze. Everything is fire-gilded. It is a very nice patina (please do not clean your !!!). The statue is an allegorical figure in Greco-Roman style. It is the goddess of music. She has a lyre in his hand. Is it on the base of the statue a name?

The clock was made about 1870 ... 1890th. The manufacturer name is not read. Please look in the back on the clock board. There maybe a name is read. All parts of the candelabra are made of bronze. They are fire-gilded. Here too, a red marble is found. He is one whole piece of ground and polished.

A very very nice ensemble! Everything is complete and the condition is excellent. There is even still the original key! Congratulations!"

So far I have had four people tell me NOT to clean the patina. I thank you all for this and yes, I got the message loud and clear...leave it alone LOL!!!
