Brooches are perhaps the oldest type of jewelry. When man first took to wearing something more than a loin cloth, there emanated the necessity of holding the cloth together. The thorn or "spina" was probably the first of these pins, with pins of other material, like flint, found in the caves of the Paleolithic age. Pins of bronze were in common use during the bronze age.
