* ear-rings.
   These rings were not worn as mere ornaments, but for
   superstitious purposes; perhaps as amulets or charms, first
   consecrated to some false god, or formed under some
   constellation, and stamped with magical characters.
   Maimonides mentions rings and jewels of this kind, with the
   image of the sun, moon, etc., impressed upon them; and
   Augustine describes them (Epist. 73,) as used for this
   execrable purpose.
