Awesome older lamps found in old garage

Can anyone tell me anything about this lamp? I have two matching lamps. I was sitting in someone's garage the other day, & I spied them in the back corner behind a bunch of boxes. The looks of them intrigued me very much. So I asked if I could buy them from her, with her reply she said I could have them. I am so excited to own these beautiful pieces of work. Unfortunately I don't know much about them, age, origin, let alone value. But I'm not looking to sell then, just hang on to them for a long time.
