This is a fish hook.
It is from El-Sheikh’Ibada (Antinoopolis). Fish provided a staple food, especially for the poor who could not afford meat, over a long period of time. Egyptians used nets and traps to catch fish to sell. Angling was more a sport for the better off Egyptian, who might have his own fish pond in his garden. He could sit with a rod and line waiting for a fish to take the bait. This is a fish hook. It is made from a copper alloy. It is 1,400 to 1,600 years old, dating to the Byzantine Period (AD 401-600).
