ANGERONALIA, in antiquity, solemn feasts held by the Romans on the 21st of December, in honour of Angerona, or Angerona, the goddess of patience and silence. Festus and Julius Modestus, quoted by Macrobii, Saturn. lib. i. cap. 10. derive the name from angēna, "quinsy;" and suppose the goddess to have been thus denominated, because she presided over that disease. — Others suppose it formed from angor, "grief, pain;" to intimate that she gave relief to those afflicted therewith. — Others deduce it from angeo, "I press, I close," as being reputed the goddess of silence, &c.
