σάλπιγγος [1 verse](noun sg fem gen) "Trumpet" is salpigx, which means "war-trumpet," but it is also the name of a bird and a kind of comet. -- "Trumpet" is translated from a Greek word that means "war-trumpet," but it was also the name for a type of comet. Given that the context of the last several verses refers to heavenly bodies and omens, a "great" comet makes more sense than a "great" trumpet, especially since the word "sound" does not appear.
