Horse-and-Vehicle Sound Character

It is a classical sound-word for horse-and-vehicle noise.

A Western Han poem by Yang Xiong uses 駍 in a scene of horses, riders, and imperial chariots; there, it evokes the procession’s rolling noise.

Two historical dictionaries preserve other senses: 玉篇 records a horse’s name, while 集韻 places 駍 in its entry for the sound of horses and vehicles. Another gloss applies it to a dense mass of sound.
