The oldest, found in Palestine, is believed to be about 9,000 years old - which seems reasonable in that the 1st verse in Job 41 asks, " Canst thou draw out leviathan with a hook?"
Well, this one is a bit newer. Hand carved in wax and cast in Sterling Silver, my version is unlikely to catch a leviathan, but it'll look pretty good hangin' around your neck from an 18 inch braided leather choker.
Shoot me an email if you'd like more info on it.
