FIBULA, in Antiquity, was a sort of button, buckle, or clasp, made use of by the Greeks and Romans for keeping close or tying up some part of their clothes. They were of various forms, and often adorned with precious stones. Men and women wore them in their hair and at their shoes. Players and musicians, by way of preserving the voices of children put under their care to learn their arts, used to keep close the prepuce with a fibula, lest they should have commerce with women.
