This is a collection of ironwork balconies I couldn't resist photographing as our Les Cars Rouges open top tour of Paris sped by (hence all the funky angles!). According to my scholarly Wikipedia research, wrought ironwork was popular in France from the 1600s. I'm not sure, but since these were on buildings with many repeats of the same style of balcony, I'd guess that they are cast ironwork, which would have been popular around the 18th century.
I think I'll return to these images when it's time to get my gouges out and do some gold tooling. I saved the image at a rather large size, so you can click on it to see the details up close!
